Hi Jenna,
I want to welcome you to this site and let you know that this site is one the most awesomest sites.Everybody is so nice on here. Take a look around you will learn so much about this disease. I have had it for 7 1/2 years and yes I won't lie to you it is a huge monster.
With your question about hives I have them. The same exact thing they are like water blisters or I say they are like when you get burned they do the same thing. I don't much about them but I do get them they hurt like the dickens and I never know when I will get another one or where. Mine seem to stay forever it seems like and takes forever to heal. When they form and break open mine seem to turn into a huge sore,it is very sore to the touch or if I bump it it sends me through the roof and it seems like it takes 1 1/2 -2 months to heal. I don't know that is just a gestamation. Sometimes mine are very deep and those seem to take longer to heal. Yes I have had them on my hands,arms and feet. I always end up with nasty scars. All I know is they are not fun. I did start out with rsd in my left hand/arm and have not been diagnosed with it anywhere else but I feel alot of the symptoms that I have in the right arm and hand are similar to what it started out in my left hand. If you look at some of my other posts you may see what else I have been through but can't explain why.
Like I said just check this site out I think you will find it very helpful and that the people on here are wonderful.
Take care and hope things work out for you. Have a Happy New Year!

Sincerely,
Tracy
