First of all, dont self diagnose! get yourself checked out
I've had glandula fever now for about 4 months and im forbidden to play all sports incase my spleen gets bashed. Even tho i was feeling better, i decided to play Inline Hockey, and ended up barely being able to move when i got home! Ive now gotta have a scan next week and tests to see if ive made things worse
At the end of the day, it could be a torn / pulled / damaged muscle & nothing to worry about!
The only thing id worry about with hospitals is going in for an op and finding out you've had a leg amputated, or grown breasts, or got MRSA! etc!! but dont jump to conclusions, get down the docs first thing monday, and dont worry!
