Therapeutic measures were taken as a result of pain, asthenia, loss of personal independence in daily activities, gait disturbance, polymers allergy, erythema, rash pruritic.  Additional information: The day after my second shot I had pain and extreme weakness on the left side of my body for about 24 hours. I had to have assistance to get out of bed and walked with a limp. After recovering from that, I gradually developed a neurological chemical sensitivity to polyethylene glycol. My reaction to PEG includes a painful, red, itchy rash on my vulva, face, and several other places on my body when exposed to PEG in hand soap, dish soap, toilet wipes, personal lubricant and other products. I had a PEG prick test that caused me to have to go to the urgent care center the next day. According to my allergy doctor, it's not a true allergy but a sensitivity reaction. It flares up old injuries from years ago including, for example, a jellyfish sting from 3 years ago. As long as I avoid PEG, I'm fine.
