MM, I had the same problem before, but no swollen feet or hand. You'd better to see doctore just in case.

In my case, nothing was serious, but the medicine contines cortison (spelling might be wrong), which made me excited every day.

But if I stopped, the rashes came back agin.

I think I finally gave up the medicine - I was afraid of addiction and I couldn't wake up 20 hours per day.

Initally it got much worse, I use a cream and tried not to scratch.

It's not easy - but I always found something to do so that I could be distracted. It took me about two months to get over.

The true cause I found later was allergy - I was allergic to metal, masquito bites, ants, and sometimes seafood.

Hope MM get better soon.
