Hi - I Am A 55 Year Old Woman. General

Hi - I am a 55 year old woman. General good health. Been watching my blood pressure ( a little high). I sometimes have an "aching" feeling in my left arm. Generally if I lean on it. It somewhat reminds of the beginnings of when I had a giant cell tumor in my right arm just above the elbow about 10 years ago. Could this be the same thing?
