I am having Major Knee Surgery Monday, its a biggie, they are scoping it and then cutting the frt of my knee open and flipping my knee cap and taking some thing out and adding something and while I am under i am getting a injection in my shoulder and if that doesnt relieve the pain in my shoulder, I have to have it operated on after I recover from the knee surgery ( I wont be able to put any weight on my leg for at least 6 weeks)
