Re: EXTREME SORE PIP. Please help
I have had this myself a long time ago. Injected my right quad and a couple of days later there was a small lump lower than the injection site itself. Couple of days later and it was lower still until the lump finally reached my knee. There it stayed for a few more days until it dissipated. I could not bend my leg fully or straighten it. I believe that I injected between the muscle fascia and the fluid tracked down from the site of injection. I did nothing at the time and it did go away. If it isn't red or hot you'll be fine. Could maybe try some light massage or heat to help absorb the fluid.
