Thank you so much for the posts! My 50 yr old son is experiencing most of these same symptoms. He's had covid 3 times and is now fully vaccinated. He's gained 40 lbs since June all in his abdomen which is hard as a rock. Dr put him on lasix which had provided some relief...maybe 15 lb loss. Next month he goes back snd they will do complete blood panels. Dr didn't seem convinced it was Covid related. But what else could it be? Blood pressure was normal. Blood o2 normal. Lungs clear. No pain (other than discomfort from distention) and back ache. No diet changes. Very active. He's so depressed and we are worried!
