Hi, Its been 2 months since I got covid , I started doing exercises without weights since 15 days I do stretching, squats, pushups, walking daily .but I have a sharp and needle poking like pain in middle of my left sole and also same pain like in my left palm middle only when I sleep in nights not in other times it's not everyday but randomly. And also I have pain on my back of knee when I get up from toilet everyday since a week then it disappears. I'm on ecosprin 75 mg once a day since I discharge from covid as per the doctor advice. What could be the reason ?
