Hi Hazelnut!
I know they can appear anywhere... regardless of what causes the hives, taking Benedryl is a solution...you can take two at a time... Yes, I know you may feel a little tired...or maybe not... depending upon what you are working on or up to! But it will work! I know this is what doctors' advise. Sorry this is happening and good luck to you!
Happy New Year!

If you are taking other medication, you might check with your doctor or a pharmacist first...
