I was infected with covid.19 in last April. Although i recovered after 20 days without any need of oxygen and hospitalisation. Recently, after some incident i suspect that i am consuming something pothat make me feel severly week. Even after a lapse of around 7 months i do not feel normal despite having good diet. Symptoms are.. 1. Acute weaknees. I find it difficult to stand even for 10 mts while travelling in metro. Walk slowly and cannot breath normally while walking. 2. My eyes start to close heavily arond 9.30..10 pm very frequently whereas i never used to sleep or felt like sleeping unless i go to bed properly for sleeping throughout my life. 3. I feel exhusting of energy in my legs in evening when lying on  bed. 4. I feel that i am confused, cannot remember or recall things properly. 5. My sugar level has gone high upto 200 in last 3 months. During treatment of covid i was given steroids. Later sugar level came to normal. Whether i am right. Pl advise tests.
