Post covid. To do? should i don't worry?

I had covid two month ago mean i tested negative on 4th may 2021 but still I have bodyache, different kind of pain in leg. Many people who had fever, sneeze has recovered but i am still suffering even I had mild symptoms ( bodyache + mild fever) I had regained my smell appx.90% and tiredness and weakness has been also gone but one thing that is bodyache and legpain. I m confuse why I m suffering from such kind of pain because I had mild symptoms. I always think about it that kuchh bura na ho jaye body k sath... That's why I m not able to concentrate  on my study. I have done three test CBC, d-dimer and CRP everything was normal. I have taken three vitamin injection B-12 it seems that something has improve little bit... But I m in tense... Can you suggest me what to do?? Should I don't worry?
