I first notice a small pea sized lump on my upper right arm muscle about 4 inches below my shoulder about a year ago. It didn t hurt so I disregarded it. It has now grown to about an inch in diameter and a quarter inch in height and is tender and lately has been causing a stinging sensation down my arm to the little finger on my right hand. It seems as though it might be pressing on a nerve. Is this a common scenario ?? First time for me.
DEAR FRIEND SWELLING MAY BE ARISING FROM THE NERVE OR SURROUNDING STRUCTURE, PRESSING/PUTTING PRESSURE ON THE NERVE BECAUSE OF WHICH YOU ARE HAVING THAT TINGLING SENSATION. CONSULT A SURGEON. IT HAS TO BE EXCISED AND SENT FOR BIOPSY. HAVE A HEALTHY DAY.
