Hi, 6 months ago I went to the hospital and turns out I have an intramuscular hematoma. The doctor said it was small and to leave it be so it will shrink on its own. I ve gotten many ultrasounds and an MRI but they won t do anything further about it. The pain stopped after about a few months but lately the pain has been throbbing at random times during the day and I have a feeling it means something is wrong. Should I do anything about this?
