Just had an endoscopy done this morning, went well. The doctor informed my parents, though, that when he saw my lower part, which is where my stomach is, he saw some redness there. What do you think that is? Could it be anything serious? Also, right after I left, I didn't feel pain in my throat, until a few hours later, (which is now) I'm starting to feel pain when I swallow. Anything wrong with that? Thanks.
