Post Covid Syndromes. Please suggest!

Hello Doctors Very Good Afternoon               Sir/Madam                                                        After recovering from covid I completed my 36 days At home, where I have been going with some post covid syndromes & various manifestations. Commonly like pain in mid of abdomen in right side, behind of neck pain and back of head pain, sometimes burning sensation of skin and over my feet, skin colour got darkened as already my skin is brownish, joints pain and numbness , But recently in last two, three days I have developed a mild jaw and gum pain, very rare blurring vision. So now I'm going afraid about any fungal infections or not! Although my all types of diagnostic tests were normal while the time of covid treatment, such as-CT thorax scane, d-dimer, and others.Even I wasn't gone for any steroids accept of antibiotics. But one thing is that before covid I was suffering from vitamin d deficiency including joints pain and striving for a better Immunity. please suggest
