I am 59 and shoot IDPA and 3-gun. I have lived an interesting life...sports, horse breaking, moto-cross, martial arts, etc, etc...injuries and more injuries. Every injury you receive when you are young will come back to live with you in later years. I have Osgood Schlatters in my left knee, Arthritis in my lower spine, aches and pains in my elbows, shoulders and knees and just finished 8 months of rehab after major right shoulder surgery. If I can do it you can too
See an Orthopedic Specialist and ask about Physical Therapy. When I get ready to head to the match I get my gear, ammo, hearing protection, safety glasses and take my Naproxen
