Nasal spray flu vaccinedrip, he gave me flonase. I have been taking it. But two and a half months later my glands are still swollenSwollen glands(did not get smaller or larger yet). I am just concerned about cancer. I read about HodgkinHodgkin's disease, liver involvement
Hodgkin’s lymphoma
Non-hodgkin's lymphoma's disease. I go back to the ent in a few weeks but am really stressed out about having cancer. I also started the other day with a small rash on stomach it looks more like an irritation not sure if it has anything to do with my glands swollen. I also had ear pain in the beginning but better now with the Flonase. Why would my glands stay swollen? How long does it usually take to go down? Could it be cancer? Thanks.
