My husband has a baseball size lump on the top front of his shoulder.  It feels like a soft ball, but squishier.  It is under the skin.  He had not noticed it until tonight.  Could something this large, grow this fast?  There is no pain, it just feels tight when he raises his arm out.  It looks quite odd.  Any ideas?
Hi, Dear,Thanks for the query to Chat Doctor.-I went through your query in-depth and Understood your health concernsRemedy and Cause-In my opinion lump in front of top of the Shoulder-is Sebaceous Cyst.-But could be fibromyoma/ Lipoma-as being painless went unnoticed till this time-So growth is not in a day but over many months or yrs. Its only today you noticed remedy advised-a-Consult an ER surgeon.b-Get the Clinical reasoning from Him. If its SEBACEOUS CYST-Excision after Nucleation in tools the curative treatment for it.c-If its benign tumor suspected by your Surgeon-FNAC BIOPSY would fix the tumor nature and would plan treatment by Excision / Nucleation of the benign lump. Hope this would help you to work a plan with your doctor. Wishing you early and fast recovery. Wellcome to my Chat Doctor Clinic for further queries in this matter. Wishing you Good Health ASAP.
