Doctors, pharmacists, and other medical professionals: is this a drug allergy, or am I needlessly worrying?

On Thursday, May 20th, I was prescribed Voltaren (Diclofenac Sodium), 50 mg, 3x a day to reduce inflammation in my knee. This prescription lasted 7 days.
On Tuesday, May 25th, I noticed the beginning of a rash on my right (injured) knee. By Wednesday morning, it had evolved into a full rash on the inside of my right knee. On Thursday, it had spread to the outside of my knee (ergo, entire knee is rash covered). I started taking Reactine (Cetirizine) 10 mg a day, and applied copious amounts of Betaderm (Betamethasone Valerate 0.1%) cream.
Thursday morning (May 27th), my Voltaren prescription ended. I saw a different doctor for my knee (also because at that point, other than the rash, it was swollen and hot to the touch--apparently I aggravated it somehow), who prescribed me Celebrex (Celecoxib) 200 mg, 1x a day. I began taking Celebrex on Thursday afternoon.
Important: the rash began before I started Celebrex, in case I didn't make it clear.
I have been taking Celebrex and Reactine on schedule since, while still using Betaderm cream. I have not used any lotions or whatnot on my leg and in fact, the only thing touching my leg nowadays are ice packs for said knee. Food-wise, I haven't eaten anything I haven't eaten a million times before, so I don't think it's that.
The rash on the right knee proper has began fading a little. However, the rash is spreading and has spreaded to my right thigh and started to scatter to my left thigh, although the left thigh has not started itching. Since my left leg is completely healthy and thus I haven't done anything to it (creams, lotions, medications, anything) I don't think this rash is the result of my direct actions.
I have sought medical advice--both the doctor who prescribed me Voltaren and the doctor that prescribed me Celebrex don't work on the weekend, and thus I went to a walk-in clinic this morning. That doctor basically said "it's localized, don't worry, I don't think either medication is causing it, keep eating your medications, using the cream, used cool compresses and eat Reactine" and sent me on my way. (He didn't do any diagnostics like blood pressure or anything. Was he supposed to?)
Anyway, I wouldn't worry...except that the rash doesn't seem to be getting better. It started before I started taking Celebrex, so I was wondering if I may be allergic to Voltaren (and the timeframe would match the ~1 week time for drug allergies)...but, if so, since I stopped taking Voltaren on Thursday morning (May 27th), why am I still having a rash??
(Rash = pink patches, sometimes raised wheals, with the more severe ones having red dots in the centre.)
I am not suffering any other medical symptoms other than the rash, as far as I can tell. I am also on birth control (Yasmin), although I've been on that for months and haven't had side effects past the initial acclimation period.
Am I suffering a drug allergy? To which drug, if any? I'll probably call the doc that prescribed me Celebrex on Monday (assuming he works Monday, I'm not sure; he's part of a larger clinic), but I'd like the Hive's opinions.
