hello -   41 yr old female.  5'7" 150 lbs.   For the past 6 mos, been having severe shoulder pain when moved in certain positions.  Not all the time.  If trying to reach behind me, or raise arm - get pain, but then subsides.  Most recently have had lower arm numbness and not constant, but very consistent thumb twitching for about 2 weeks.  Can they be related?  What type of doctor should I see?
hi,most probably you could have has a problem with your shoulder like frozen shoulder,or neuropathic pain mostly due to radial neuropathyyes both your complaints are  interrelated.please practise regular physiotherapy exercisesplease undergo  MRI scan of the shoulder joint, &  cervical spine to rule out any injury to the nerve endings .please visit orthopaedician & neurophysiciantake care
