My uncle (age 78) was infected with covid last month. He got pneumonia hence hospitalised and lungs effected 40%. Its now 3weeks he has returned home, but the problem is his ankle is swollen and he is unable to realise while urinating and pooping. hence diaper is must for him. he is unable to walk because of weekness may be..we are unable to taki him to doctor also.most of the time he wants to lay down..also he is not feeling to eat regular diet, unless its a spicy or junk food. he has sugar PP 280 and Fasting 110 His LFT test were ok, createnine 0.5 Urine test is fine. CRP is evalated to 100 Any idea what kind of infection it could be? why the Crp is high? is it because of swollen feet? and what can be the reason of swollen feet?
