From the last few days I noticed weakness in my body and body aches that feels like miserable sometimes.i attend classes and when I do step up the stairs for 2 floor I was always out of breath,head thumping like how our heart beats more accurately,it pains a lot . My eyes pains and there is light sensitivity that I mostly use my devices at the lowest brightness.my head aches sometimes and I feel lost and sudden dizziness.I do not know what is wrong that's why I wrote this to get an idea what this could be.
