Thanks. I did have an MRI of the soft tissue done in the evening when the area was very swollen. The technician tagged the spot, however, nothing abnormal appeared. The only note was "can't rule out fatty deposit." Not sure what that means..
I think I'm going to request a biopsy. My next visit is with a Rhuematologist. Would it be appropriate to request that they do the biopsy?
Thanks.
I may not be the best person to answer your question as your problem seems to be outside the realm of neurology and neurosurgery
If the swelling is only at night, I can see how it might be difficult for the doctors to obtain a sample at that time, unless you were already admitted to a hospital for something else.
THere are nerves that pass close to this region to supply the arm, but without symptoms in the arm, they are likely not affected.
Unless the diagnosis is clear on an MRI or CT, a bipsy of the tumor or fluid might be a good idea
Good luck
