Again covid positive report + chest pain

Hello... I was tested positive for covid19 on 7 April. I was taking some medicine for it but then breathing problems started and I was admitted in hospital. I was there for 4 days. Doctor said I'm fine and I discharged from hospital. Even my CT scan was normal. I had breathing problem again and again got admitted in hospital. Even though I had trouble in breathing, my oxigen level was always 95+. Now after all these treatments from different doctors, I again took covid test on may 10. My rapid antigen test was negative but rt pcr report turned out to be positive. I started taking covid medicine again but then the chest pain started. My left hand is paining and also numb many times a day. My ecg report is normal. My chest x-ray is normal. Doctor is saying that echo test is not needed but the pain and numbness in my left hand is still there. I don't know what to do. I'm too stressed to think straight. Please guide me.
