Advice for a (probably) pinched nerve? Good physiotherapist? (Tokyo)

I've had a tingling/burning sensation in my left shoulder/hand for about a week. A doc that I saw in Tokyo thinks I have a pinched nerve and told to come back in a week, but was rather vague about what to do in the meantime. I have no health insurance so I would prefer to not go back, but I just noticed the tingling starting up in my right hand as well. [more inside]
