Additional information: Received booster 06Dec2021 with the flu shot same day and same arm. I had a rash around the injection site along with some swelling. These went away a few days later. On 18Dec2021 I noticed my hands were very itchy. It progressed the next day 19Dec2021. Any scratch turned red with welts appearing on arms + legs. I noticed the skin writing on 20Dec2021 along with full-blown body itch and welts, hands started to burn and it was mostly pain instead of an itch. I tried Epsom salt baths with temporary relief, body serves, extra lotion with no relief. I Googled and came across chronic spontaneous urticaria and treating with antihistamines. I took off brand Benadryl and Claritin. It helped to manage some of the unbearable itch but hasn't helped with welts or pain in hand. I found out the pain in my hands was due to pressure contacts such as lifting something heavy/gripping tight. I started with 3 Benadryl a day but started to limit to see if it would subside on its own. Since 05Jan2022 I've been taking a Claritin as needed (hasn't been too often). I wear clothes to cover arms and legs to prevent scratching. I'm sensitive to my hair brushing over my skin. This condition also appears more at night but I'm still able to sleep. I've also had some heartburn/acid reflux with nausea most days. Still haven't seen a doctor. Joined a support group on social media to follow my advice, not doing any diets. 3.5k members chronic spontaneous urticarial after covid-19 vaccine support group.
