Post covid syndromes. Are occurring.

Dear Doctor ! it's been almost 21 days completed my home Isolation, and recovering. But still there are some post symptoms presenting such as sinusitis like headache, a mile eyes pain, hot flush, a feverish like sention upto afternoon, and sweating alot specifically forehead areas, mild itchiness and rashes, joint pain like knees and elbows including lethargy. Even though I took regularly proper medicines and other precautions and as a reminder I wasn't used any steroids only antibiotics were given to me. And before the time of covid I was treating as an arthritic patent So should be worried any kind mucus related issues or some other infections or its my previous arthritis based issues are occurring. Thanks 🙏
