Hi, may I answer your health queries right now ?  Please type your query here...  My physical therapist just found a hard, stationary lump on the middle of my back. She and the head therapist dont think it is a cyst, as it doesnt move.  I use a cane with my left hand and assumed it was a tight muscle.  What are the other possibilities?  Thank you.
Hi. Thanks for your query and an elucidated history. Read and understood your history of your Physiotherapist noticing a hard immobile lump at the back which they do not think is a cyst in the middle of the back. You use cane with your left hand and assume can be a tight muscle. My thoughts
