So I’m not sure if I have osteoarthritis, my right knee has been bothering me for about three weeks now. So what usually happens is after doing something somewhat physical like going grocery shopping or just simply walking around a bit my knee gets really tight and after that goes away it starts hurting. But not like constant sharp or burning pain. It’s more of a pulsing pain, like your fine one minute but in strong pain the next and the cycle continues. Anyone else experience this ?
