Thank you for your reply. Yes, I believe they need to dig deeper also but I fear they are running out of things to test. I have tested normal in every single test I have had…which is a lot. Oddly enough, the only tests they find stuff are the CT scans. Atelectasis, retroperitoneal and portal adenopathy and other weird stuff. This is day 11 of the H1 and H2 blockers. I will stay on them until at least my next Dr appt in two months.
