hello, how long does your bumps last if you dont scratch? try applying Ice to help with the itch. you said they move around mine does too.
if I dont scratch they finally give up torturing me and go away..sometimes more pops up and sometime I get a break and dont get them for a while. I found stress is my biggest trigger.
I have and get hives..mine is the dont know, cant cure kind. its called uticaria..spelling is off..you can do a search on the boards and find some very good information on hives that might help you.
I have had them for almost 10 years now. the mosquito bite size ones, the large area of solid hive that itches but hurts very bad if you touch it much less scratch it..they can also feel like a burn, and last but not least the giant sized goose egg knot hives..these hurt when they pop up. (its more of a sting itch)
scratching is the worst thing you can do to them. and I know all about learning how to drive stright to crazyville with the itch.
if you have not changed anything in your eating habits, laundry soap, shampoo, bar soap, tooth paste, new pet in the house? Stress level??? I would go see an alergist and have the allergy test done to help you name your bumps!! and maybe find some relief.
good luck! ~take care~
