I Had A Laparoscopic Surgery This Morning. I Have My

I had a laparoscopic surgery this morning. I have my doctor's cell phone number and plan to call him tomorrow. In the mean time I was wondering if someone could tell me why I have a lump on my tongue. It isn't very sensitive and blends in perfectly, I can only really tell it's there when I stick my tongue out and can feel it on my lips.

Also I am experiencing bladder retention. I am able to urinate, but it comes in small spurts often. They are slowly becoming longer, but I can't get any sleep because I have to keep getting up to pee! How long can I expect this to happen before it returns to normal?

Thank you!
