[|Human|] I have a lump around the front of my shoulder that is about the size of a golf ball, it is fairly soft when my arm is relaxed and a bit harder when I lift my arm. It does not hurt, however now and again I get an achy pain in my arm. I have had an exray and the doctor said it showed nothing, but clearly I have a lump? Should I be concerned?
[|AI|]  Hi! Thanks for writing to Chat Doctor describing your problem of a lump on the front of the shoulder! After going through your description of this kind of common lump, if I were your family physician, I would like to consider following possibilities as per my experience of ultrasound and needle biopsies:1.normal fat/muscular fold2. Benign skin/superficial tumor like lipoma, neurofibroma or dermatofibroma3. Benign cysts like sebaceous cysts, lymphatic cyst, bursa, ganglion or hemangioma4. Collection in the joint5. Enlarged lymph nodeTherefore, it is not a thing for worries but still you may confirm its nature by ultrasonography and possibly needle biopsy to relieve your tension. Regards,
