I have had a bad back for sometime and been to a chiropractor which has been of great help but realised that i have a lump under the skin of the left lower side of my back it is not painful but i do not have one on my right and so dont know if its simply a strained muscle or something else.
Hi, If the lump is not painful, it is unlikely to be a strained muscle. A painless lump in this area may be a lipoma or a sebaceous cyst. If it is not causing you any trouble, then I suggest you need not worry about it. If you want reassurance, then see your doctor who will be able to make a judgement by examination and possibly a scan. Chat Doctor.
