I'm really worried about him. He recently got over COVID but now has this lung infection. His HCRT was at 1525 back in May, but when he got out of the hospital at the end of the month, it was down to 1125. His other tests like CRP and D-dimer seem normal, but he's been having some issues. He gets constipated, and in the mornings, he starts coughing a lot which gets better after he freshens up and burps. Similar thing happens after dinner; he coughs until he belches and then it's like back to normal. He keeps feeling like there's something stuck in his neck. Plus, he's type 2 diabetic, which concerns me. Can you suggest some medication or treatment that might help him?
