My left knee has been giving me alot of problems,well I got out in the yard today mowed the yard (PUSH MOWER)and pulled some weeds out of the flower beds.Now for my question my knee is swelling up and I can't put and presure on it and when I do try to walk on it it pops and hurtys like you would'nt belive.So what do you guys think?I can not see my Rhuemy because he uped and left and I see my pain doctor for the first time on sept14.So any one with some input would be great.
