So i've been diagnosed with mono. They aren't sure how long i've had it, but i've been having symptoms for about two weeks. Well, just a sore throat in particular. I went to see my doctor yesterday and he said to be careful so that i don't rupture my spleen. He also said he couldn't feel any inflammation in my stomach so my liver and spleen are fine now. I'm not sure if that means I can go on roller coasters or if i can't

I'm going to los angeles in two weeks and i'd rather not sit out on the rides but i wanna be safe too.
Help please?
