Hi ya all, I seen alot of comments on this but No one seemed to have a answer at all, my leg's painful burning began along with extreme tiredness, rundown feeling, and tender area near shoulder area, also all over achcy feeling about 7 yrs ago, & no drs could give me explanation, I finally went to a pain specialist after 4 yrs of this  who still didnt give me a answer, then 1 day hi P.Asst came in and sat & really listened and told me it sounded like fibromayalgia, well  bingo all what was supposed to be in my head as many drs said finally had a name so she added some new meds & it was starting to help alot, then then 2 yrs ago the drs child died from being left in backseat of car & he started cutting patients, so I found someone new, so I now see a psychciatrist & pain dr, who has me on proper meds, but yes I had at 1st the painful to touch area in shoulders, then to my upper arms & upper chest & the worst that has stayed w/me and has the most extreme flare-ups is my upper thighs, i can only describe that it feels like someones poured gasoline on that area & set it on fire & now in past yr is the worm under skin feeling, so what I am saying regardless keep asking your dr if this is what it can be???? I take nerountin 1800 mg a day & that helps for nerve pain, plus many other meds, but please have it checked cause if this is what you have its just the beginning, and No its NOT in your head as many drs told me !! best wishes & pay it forward somehow someway everyday, even with just a hello & smile to someone....
