Hello again Zach
I don't think your conditions are related to each other. You just got dealt a bad hand. People with Parsonage-Turner typically make nice recoveries (some quicker than others). The important thing (and this might be a bit too late to tell you) is to rest and not lift weights at all while you're recovering. Doing so will prolong your recovery. I stayed out of the gym for nearly a year. It was incredibly difficult but it allowed the nerves to recover properly.
Yes, I had the pain you are talking about and it absolutely sucked. I never took any meds or had any type of therapy. There really isn't anything that can be done, unfortunately. You should still go to a neuro to get evaluated. You actually should have gone long ago. Hang in there and be patient.
