Should I ask for accommodations at my college?

Hi! I've been dealing with HS for this past year. Flare ups haven't been horrible but I feel like they might be getting worst. Today was my first awful flare up, extreme fatigue, lots of pain and feeling a bit sick. It left me in bed all day and I felt like I couldn't move without pain in the boil. I have classes twice a week, I don't drive so I have to use busses and the train, it's about an hour long process. Now I'm worried if I get a flare up as bad as today I might have to miss some classes because there's no way I'd feel good enough to get to class when it gets this bad.

I'm just wondering if asking for accommodations (classes have 4 missed class limit and accommodations will let me have more time off if I need) I'm just worried that this might not be serious enough to require that but also I think it might be necessary.
