Talk to Cosmetic Surgeon on Joints Pain

Aoa I am suffering from AF since last 6 years. I am on blood thinner. I had suffered from COVID in Ramzan. I didnt get high temps but i had so much pains in body and fatigue during that time. I took double dose of vitamins like CALC and surbex z to recover from extreme fatigue for fasting. I stopped taking vitamins right after ramzan. Since then from Eid day 3-4 i am facing extreme pains in hands and feet.( joint pain) i wake up in the morning with stiff joints. By the time and movement joints get mich better. But as soon as i sit and relax for even 2 mins in the day time, the joints get stiff again. Im afraid if its the sign of arthirits or just corona side effect? I am unable to properly do my tasks. My hands are not enough strong to hold stuff now. I get tired so easily. I used to do exercise alot but bcz of these pains im unable to do all that. Can someone please help in this. Thanks.
