I understand the frustration and the desperation. It is hard to imagine your exhaustion living with CFS, not being able to sleep and dealing with this persistent allergic reaction.

I know you are looking to talk to others who have made similar experiences. Some members have talked about allergic reactions related to COVID, albeit not necessarily to Paxlovid, in these discussions:
- Newly developed allergies, excema in ears

- Post COVID skin conditions: What can I do to control the reactions?

- Post covid itch and hives

- Post COVID-19 skin reactions: anyone else?

Venting and being emotional is a-okay here. You've got a lot going on and finding answers is really hard work.
