<human>: 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.
<bot>: 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:If this would have a a tight muscle, the Physiotherapist and the Head would have definitely understood it as a tight muscle. The best way to get a proper diagnosis is:Get a clinical evaluation and examination done by a General Surgeon or an Orthopedic Surgeon. Get further investigations. Ultrasonography with FNAC may help in the initial stages of investigation. MRI will be confirmation. The treatment will automatically depend upon the findings.
