hello, im a 17 year old female. ive been having terrible arms and leg pains (like after an intense workout), first i had arm pains-the arms pains were so bad one night i almost couldnt breath because of the panic and stress of it, 2 days later my right arm completely recovered and the left went down a little, however then i had leg pain in both legs. Near the knees, again now my right leg has recovered although the left knee still hurts, and the pain in the left arm has gone down to my fingers and lower arm, pain killers have no effect what so ever! I was thinking about seeing a doctor (sence i hadnt done anything to cause this) but i was sick and nauseous for 5 days before it started, so family told me it was probaly a virus . Im worried its a blood clot because 2 days before it started i was flying interstate, also on another note in the last 4 months i have had reacuring hives , and was also told this was viral and would go away, which it hasnt.
