I’m having this exact same issue. Timeline is as follows:
Moderna #1- No issues whatsoever
Moderna #2- Some fatigue, mild fever acutely. Then had a few days of hives 2 weeks later but they resolved spontaneously
Moderna booster Dec 13- Spent 2 days in bed. Fever, fatigue, swollen axillary nodes on same side as shot. Dec 25 hives all over my body with severe itching with any kind of pressure. Worse at night and after a hot shower. Also developed dermatographia which I’d never heard of prior.
I saw an allergist at the end of January who immediately recognized it as related to the vaccine. She’s actually running a study as she’s had many patients come through with these symptoms related to the vaccine.
Meds: First month she had me take 2 Allegra in the morning and 2 Zyrtec at night. This worked and I had no issues.
As of March 1st she had me start tapering the antihistamines so I’m now doing one Allegra in the morning and 1 Zyrtec at night.
I feel like the itch is returning but the dermatographia is better. Not gone, but better.
I feel like if I stop the antihistamines, everything will come back full force. I’m enrolled in the study and getting bloods drawn next week.
A bit relieved that I’m not alone.
