Nancy is right. I've suffered from PCS for almost a year and a half now and have similar symptoms. Prior to my symptoms, I lifted weights and ran on a daily basis. Since the symptoms started, I haven't been able to do anything physical at all, let alone lifting or running.

My advice is take it easy, as hard as it may be. I've tried months upon months of chiropractic as well, and it was no help. Chiropractic is likely not going to help with PCS.
