I have MS and I am currently in an entry level master's degree nursing program. For the post part, my symptoms have been under control, with the exception of severe fatigue in the summer months due to the heat.
I was in my med-surg clinical and as June and July brought hotter weather (which exacerbates sx), my fatigue was getting worse. I would lay on the couch before my PM clinicals wondering how I was going to find the energy to even get up off the couch!
I went to my neurologist and he gave me a script for provigil, and that helped a lot.
You can do this!
One of my class assignments was we had to spend a day with a call center "ask a nurse" for Kaiser hospital. Patients call and to get advice. At the call center I saw a few nurses answering the calls who where in wheelchairs. So, even if you symptoms cause a degree of immobility for you, there are always options in nursing to keep us working.
