Health problem with stress. Is bad.

I actually cant share my feelings with anyone except u people.  I'm having worst heath problems madam/sir. I had knee pain from april ,now my knee pain has almost reduced 99%. But other problems have started. I had severe eye pain 1 week back that went away ,then I had nausea and vomiting sensation for 3 days I couldn't eat anything.  However that went away after 4 days. Then now I'm having pain in my left chest from 3 days. I m having pcos from 2years. I used to get periods 7-8 times a year. From april , no periods at all. I'm sad ,tensed,worried , frustrated and dont know What to do. I feel like going and getting tested in hospital but I'm scared whether I will bring covid home to my parents who are old. In Bangalore covid situation is bad..
