I've had that several times. It didn't last long but is just another annoying thing to deal with.

I get that also... it's lupus.. one of the many flare ups..

I would just confirm that it's not a reaction to medication. I had it happen to me inconsistently and it was still the medication.
When I say inconsistently, I mean I took the medication daily but I didn't have a reaction every day. Yes this diagnosis will have you all over the place.

I have to. I thought I had eaten something that I had a reaction to. Wow lupus has really has changed my life and the lifes of everyone who has it.

If it gets any worse go to the urgent care. If it is an allergic reaction you need treatment.... Hope not. Hugs...
