relapse tetanus reaction?
I had a tetanus vaccine in August. Had typical allergic reaction described elsewhere in these threads - Arm swelled up, had hard rock-like swelling near injection site - it was itchy and uncomfortable for like, two weeks.
Anyways, over the last two days (it's February now), my arm has again become extremely itchy and tingly. It's not a skin rash - there is no superficial rash - the arm looks normal except for being kind of swollen. It's a deep itch, feels like ants are crawling around inside my arm. I've tried using goldbond itch powder, tried a spray-on anaesthetic - nothing helps.
It feels quite similar to the initial reaction I had, but is also present in my forearm whereas before it was localized to my bicep.
Has anyone ever heard of a relapse (for no apparent reason) allergic reaction six months after the fact? What else could this be?
I am going to gnaw off my own arm soon. It's driving me insane!
