Talk to General Physician on Ulcer But Not Yet Proper Diagnosed

My mother is suffering from painful pain, she is continously taking pain killers for more than couple of years. 5 years ago my mother was diagnosed with brain tumor named manengioma and lateron after surgery small wound took place in the foot near toes after that we visited skin specialist and the matter was resolved but after some months the same wound rose again and it increased day by day. We had paid visit to almost every hospital in karachi including liaquat and aga khan but it was not properly diagnosed.
