COVID AND AFTEREFFECTS. This happening.

Hello, I was first diagnosed with covid on 10th May it was very mild only diarrhea for one day and no other symptoms but after a month I started having fever of 103 doctor told me to redo the covid test and again I tested positive but this time I had no smell and continuous diarrhea for 3 days and fever was coming and going for 5 days. Now today I feel normal but have mild fever from last 2 weeks between 99 and 99.4 i do not feel any weakness no other problems. Did all test suggested by doctor. Also did sonograpy of stomach and liver as suggested by gastroenterologist but it was also normal. Crp is raised at 27. Currently having Curex 500 ( Cefuroxime Axetil tablets IP), and stelac. Why is this happening..
