I just start to feel worried because my personal health has been weir this year? I try to take care of myself but i've been sick a LOT. And last night I had massive leg cramps for no reasons and today I had very blurry vision at some point and since I just finished covid I'd rather not get sick again?

whatever this is?

I goy myself some magnesium and potassium to help with the cramps, hopefully. I'm just... going to bed super early tonight and see if it somehow helps
