I just started antibiotic for strep today and I have had it for 5 days. I have run a fever constantly during that time. I just woke up and went to get more water, became extremely nauseous and went to lie down on tile. When I did, my body and arms began a very painful tingling, I couldn t move them. It felt like they were so swollen I could barely bend my fingers and my appendages were so very heavy. It also began to move into my legs and got as far as my knees. My husband put cool rags all over me. It lasted for about 3-4 minutes. Maybe longer. Now all my joints hurt.
