Pea-sized lump in underarm. Should I fly home at once, or can I wait and see if it improves?

June 17, 2009 6:47 PM

You are not my doctor, but I need your advice to help me decide if I should fly home and see one immediately, or wait things out a bit. I have a pea-sized lump in my underarm that is a bit painful when touched. I am a Canadian, uninsured in the States. Male, mid-twenties.

Until I discovered it, I had been using an aluminum-based antiperspirant (Mitchum) on a daily basis, more frequently than I usually do given the muggy weather. On Sunday I noticed it and promptly stopped. Since then its size has remained constant and the discomfort too.

I can fly home and see a doctor, but that would involve reneging on some important commitments. Seeing a doctor here is not within my reach, particularly if it involves paying for tests. I've called my family doctor back home but he is out of town at the moment and so unable to dispense advice on the phone. (Other doctors are available, though, if I go back, obviously.)

I've been experiencing a tremendous amount of anxiety lately (unrelated to my health) and have taken NyQuil several nights in a row to help me sleep. (Doxylamine is the only OTC hypnotic that works for me.) Otherwise healthy and not on any medication.

My plan is to wait a bit and see if it improves. Am I being reckless?

I realize you are not my doctor, that this is not substitute for professional advice, and absolve you of any responsibility.

This could be any number of things ranging from mostly harmless, like an ingrown hair or boil, reaction to an infection elsewhere (kind of like cat scratch fever) to a sign of something more serious. However, the non-serious causes are FAR more likely. I had a lump under my arm similar to what you describe when I was a teen, and it turned out to be a mild infection. There are a lot of things that would be helpful to know:

Have you inspected the lump to see if it feels hard, or soft/fluid-filled, warm or not warm?

Does the lump seem to be under the skin, or something to do with the skin itself?

Do you have any other symptoms? Fever, aching, sweating, malaise?

Do you have any cuts, abrasions, etc., anywhere else on your body that could be infected?

oh yeah, and IANAD

I would have it checked out if I were you. I do not understand, however, how it is that you can afford to fly to Canada but you cannot afford a single doctor visit in the U.S.

IANAD, but a couple friends of mine have had the same thing you are describing, which turned out to be a cyst. Both of them had theirs removed by a dermatologist, but they weren't dangerous, just annoying and possibly painful.

It's probably an ingrown hair.

An uninsured doctor's visit is probably not as expensive as you are imagining. Granted, if extensive testing is required, it might be, but you could surely at least get it looked at without flying back to Canada.

How long have you been out-of-country? Your provincial health coverage may have lapsed, and you'll have to pay for the tests anyways. (i.e. In Ontario, you must be in-province for 153 days of the past 12 months and other provinces are similar)

Have you tried popping it?

Thanks for the answers so far.

It's hard, below the skin, and not any warmer than the area around it.

I do not understand, however, how it is that you can afford to fly to Canada but you cannot afford a single doctor visit in the U.S.

I would actually be taking the bus, not flying. I wrote "fly" because the possibility of taking the bus suggests that the distance is not far (in fact, it's a 12-15 hr. ride) so fly seemed like an adequate shorthand.

Pop it. Painful at first, but it hurts so good afterwards.

by coincidence, ThaiVisa has an on-going forum thread about underarm lumps.

scary.

Nevertheless, I think you may be surprised how inexpensively you can get a doctor to look at it in the U.S. before you go all the way to Canada for treatment.

My husband gets lumps similar to what you have described in his pits when he uses an antiperspirant with too high a percentage of aluminum. This has happened to him several times. In his case, he stops using the antiperspirant, stinks for a couple of days, and then the bumps go away. I've also had male roommates with this problem, but interestingly, I've never known a woman with it.

This is just a story about my husband's pits. Lumps are scary, and your pits may have nothing in common with my husband's pits.

Defreckled, I used to get it all the time in my early twenties. It was from deodorant and exactly like you and the OP describe.

Do you have a walk-in, non-emergency clinic in your area? If so, go see a doctor there for a quick visit and assessment (in my area, the cost is about $70). They'll be able to tell you whether it's something harmless or whether it's something that requires further diagnosis (at which point you can make plans to return to Canada if need be).

Getting the assessment is probably a lot cheaper than heading home.
posted by bonobothegreat at 8:01 PM on June 17

Waiting two more days without antiperspirant to see if they go away is even cheaper than that. Then go to a doctor.

If you decide to wait a few days, just watch out, in the meantime, for any systemic complaints -- joint aches, fever, ill feelings overall -- that might indicate a serious infection.

It's probably a swollen lymph node, and probably nothing to worry about. It should stop hurting after a few days and the swelling will last a few days after that.

IANAD.

I found this about how antiperspirants work on Secret's site.

As with other aluminum-based deodorants, the aluminum zirconium trichlorohydrex GLY in Secret Clinical Strength Deodorant/Anti-Perspirant works in two ways: one, its capsules clog pores (preventing moisture release) and two, it absorbs moisture from non-clogged pores (hence preventing malodorous-ness, as bacteria breakdown sweat and release a scent ). The net result? Dryness.

Maybe your pore is seriously clogged. I'd try washing the area with dish soap or wiping it with rubbing alcohol and see if it helps. If it doesn't go away or start getting smaller after a day or so, I'd go to a doctor.

If you're worried about money, call around and say tell the office you don't have insurance and ask what they charge if you pay cash. Many doctors by me are giving patients a cash discount if they pay upfront so it's not so bad. Non-insured patients who pay cash save them money since they don't spend time on paperwork and some patients go and then say they only can pay part and stiff them so they like getting cash on the spot. The last time I went it was around $60 which is probably less than your bus ticket. If you do have to have tests done, then ask costs and if it's too pricey, head back home.

Are you in NYC? If so, please consider seeing Dr. David J Ores, MD, also known as The Rock and Roll Doc. He provides health care for those with low-income or no insurance, cheaply. I have never been a patient of his, but some of my friends have and recommend him.

You could try calling Telehealth Ontario. They can't actually examine you, but they can talk you through it and help you figure out how serious it might be. It won't be toll free since you're out of the province, but it will still be cheaper (and faster) than a visit to the doctor, or a bus ticket, and more authoritative than AskMeFi.

That sounds like the swollen lymph node I had a couple of years ago. I understand the anxiety--my dad died of cancer, so that's where my mind went immediately. I went to the doctor, got on a course of anibiotics, and it went away in a week. For all I know, it would have gone away in a week, anyway.

I've had the same kind of bump when I switched to Mitchum roll-on and used too much. It went away in about a week. Mitchum has one of the highest percentages of active ingredient out there.

IANAD but I believe if it is cancerous, then it is NOT sore to the touch. Soreness indicates an infection of some sort. Probably an infected hair follicle/ingrown hair.
posted by heather-b at 1:07 PM on June 18

I had this same thing happen two or three times. My old standard cure of "ignoring it" worked yet again!
posted by pantsonfire at 11:11 AM on July 1

that happened to me in college--turned out to be a swollen lymph node that went away on its own.

just keep an eye on it--if it grows quickly or others pop up, it might be worth seeing a doctor more quickly about it.

I've also had male roommates with this problem, but interestingly, I've never known a woman with it.

My theory is that it has to do with underarm hygienics & hair - girls (generally) don't have underarm hair and therefore the area stays cleaner, and sweat doesn't build up and stay around.
