I am 58 year old woman, 124 pounds 5'2".  I have had constant pain in my left shoulder up into my neck and jaw for the past 6 weeks.   I have been taking 30 mg.vyvanse for the for ADD the past 6 months.  I am a pianist - accompanist and teacher.  I first attributed the pain to "telephone shoulder" and the stress of my daughter's wedding.  Wedding is finished, I use speaker phone, still have pain.  Do you think it could be vyvanse related?
Hi,  Since u play piano u need to correct ur posture. It cud be posture related. U better visit a physio for posture correction and stretching and strengthening exercises. Hope its helpful.
