I have a marble sized lump in my mid to lower left back muscle, I can physically feel it and see it, well my wife can see it.  It doesnt seem to hurt, but recently I developed a lump in my right deltoid muscle about the size of a pea and it came on about 6 months ago and is not painful unless I push on it...  related?  possibley?
Hi, dairy have gone through your question. I can understand your concern. You may have some soft tissue tumor like lipoma, neurofibroma or dermatofibroma. You should go for fine needle aspiration cytology or biopsy of that lump. It will give you exact diagnosis. Then you should take treatment accordingly.  Surgical excision is the treatment of choice for most of the benign tumor. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
