Your body and your health both mental and physical, are very important. I don't want to sound like I'm lecturing you here, but it's always better to be safe, than sorry, right?
I know you say you have a lot of appointments anyway, but you should still make one and go. If something was wrong, you'd find out earlier, and get treated earlier. If you leave it and there's something wrong (hopefully not), what if it happens during exams and messes all that up? What if you've left it that late, that its a lot more complicated to treat and fix? What if it causes more pain whereas if you had it checked out now, it may have been a quick easy fix.
It's always better to just go so you can be relieved afterwards, rather than put it to the bottom of the pile and "worry about it later".
Good luck x
