Hi..welcome to the forum!
Hope you're going through a good spell at the moment.
I would strongly suggest you look into rectal meds as a treatment/maintenance..it may help keep you off prednisone...considering this is a life-long disease.
Tick bites could very well trigger an autoimmune response in the body....many of us don't recognise early rectal inflammation until things spread upward a bit or the most becomes obvious such as blood...you could have already been having some inflammation/symptoms without recognising them, and tick bites created an overload of your system increasing the response in the rectum/colon.
You might consider making a signature with the meds you're taking...where in the colon your UC is (limited or throughout)...etc. It has to be limited to 10 lines, spaces between lines are considered one line as well.
