I am sure I am not the only 1 to experience this. Recently my pumpers have been getting less use. During the pumping of the rifle(392pa, and c9) the 7th and 8th stroke are a lot more force than the rest as pressure builds within the valve. Once I have shot the rifle several times I start getting a sharp pain in the elbow near the funny bone. I expect this is due to something known as cubital tunnel. Which I have been told I have. Similar to carpal tunnel it's just the nerve in the elbow instead of 1 in the wrist being compressed. Not severe enough to require surgery yet, but still a comprimise for some activities. Not a fan of the meds used for relief. I was reading through some old posts on here and discovered 1 by someone claiming relief from a laser type device. Some internet searching reveals it likely a red-light therapy, or ir type treatment device. They also claim it works and has allowed them to continue using pumpers with no other treatment. Now I have 1, it has 2 frequencies of red light and 1 ir spectrum light. Supposedly the ir treatment is best for deep penetration and joint problems from arthritis to problems like mine stimulating circulation in the effected area etc. Today is day 1, recommended treatment is a minimum of 3 weeks even if you experience relief sooner. I will let you know how it goes...either way if it turns out to be ineffective I can return it. Now we wait....maybe a couple days we pump, shoot and test to see if there is any appreciable change in symptoms. Any one else use 1 of these devices? Try any other methods for relief that were successful?
