Hi welcome to Health care magic forum.
Thanks for calling H.C.M.Forum.
You are having the pain under the breast, since 2011. some times on left side and some times on right, and some times on both sides. 2 weaks ago you had pain upto right arm pits.
As you are not getting relief with regular treatment it may be due to cervical spondylosis
, or due to gastric irritation.
I advise you to consult an orthopedic surgeon. You may need to have an M.R.I. of the neck, for confirmation.
Avoid taking potato, other tubers, tomato, fish, egg, chicken, and seafoods.
Wishing for a quick and complete recovery.
