I am 48,female,in good shape and health.Two yrs ago I started experiencing right side neck/shoulder/arm pain that radiates to my upper chest,into my armpit and under my scapula in the upper back.It is sporadic pain and varies in intensity.Most of the time when it flares up,which can be evey day for a month or only once a month,it is unbearable.It is a severe pinching,sqeezing,burning pain with a lot of pressure.It radiates down my arm into my hand.The worst part of it is the pain under my scapula and upper chest.It really is excrutiating.I get no relief from any pain meds.I have had a cervical MRI, EEG-EMG,shoulder x-ray,chest x-ray,abdominal ultrasound(rule out GB problems)and several breast mammograms &ultrasounds.Everything is normal except the EEG-EMG that showed a very mild abnormality with the ulnar nerve,but nothing that the doctor thought was significant.I have had 3 rounds of physical therapy and I am currently seeing a trigger point massage therapist.It feels great when I have the massage,but the pain always,always returns.I don't know what to do next.The doctors I have seen about this don't have an answer.All I know is that before two yrs ago, I didn't have this pain.My worry is something is being missed and it is something serious.Thoracic outlet syndrome has been mentioned.I have been told it is hard to diagnose though.What other tests should I have done to rule out anything scary?Since it has been two yrs should I have any of the previous tests repeated?Your input is appreciated.
