yesterday I had consulted a doctor near my local resident. I had an arm pain which I found out became a shoulder pain the following weekend. The doctor told me I had muscle spasms, and if the situation doesn't clear if I take my Advil Extra Strength  and if my arm forms rashes or blisters, to come back again as it seemed urgent. The next day (Today) my arm seems to have formed a few rashes and before tomorrow, I really would like some answers into what it could be.
