After my first dose, I just had a sore arm and was tired the next day. I got my second dose yesterday, and I feel like I've been hit by a semi. My arm is sore, the lymph nodes under my armpit are swollen and my upper back and shoulders are sore. I have this headache that keeps coming back. I'm light headed and can't walk long without feeling so out of breath. I also have a slight fever of 100 F. I know these are known side effects, but I didn't think it would hit me so hard. My body just hurts all over. I've been taking Ibuprofen around the clock so far and it's been helping, but I was wondering if anybody else had a suggestion of what else I can do. And if anyone felt similar to me after their shot, how long until you felt normal again?
