I m a 30 year old female. I donate plasma and about 4 hours after donating. I had some pizza I could not finish because I started to feel nauseous. Then I began to feel dizzy and hot like fever hot. Followed by serve sweating lasted about ten minutes. After that I was freezing and still feel very weak. The last four days I had pain under my rib. I assumed it was my kidney s and increased my water intake. Normally my urine is very light to almost clear but now it almost seems gold or orange even with all the extra water I m drinking. I have gone to the ER twice in 2 months. The first time was because of the pain under my rib which they believed was a kidney infection but all tests and xrays came back normal. The second was because I had severe headaches that would not go away for days again all tests came back normal. I don t know if this is all linked or not but I m frustrated. I go to the hospital they see the proof of the symptoms yet no one has a clue why I m getting them. I have been donating for 8months and never felt like this afterwards a lil weak and tired yes but not pass out weak
