I currently have several symptoms that i'm hoping are not all interconnected. For starters I have a dull but firm pressure in my lower intestines pushing from the inside out. Secondly, I have seen floaters and flashers on several occasions in the last week. Next, I have a dull pain on the side of my head. Lastly, I have a cyst near my rectum.

My questions. What type of doctor should I see about this? What do you think might be wrong with me? Could this all be related to food poisoning from undercooked beef and seafood a week ago? Or can this be related to me knocking my head fairly hard a week ago?

Aside from the cyst, these symptoms are all around a week old. What should I do?
