What Might Cause A Sedimentation Rate Of 125? I Just

What might cause a sedimentation rate of 125? I just had blood work done. I am also anemic and have a problem with red bumps (hives?) all over my body (for maybe 6 weeks). I have been to a dermatologist who gave me two different antihistamines to take. I will have an upper and lower gi on Tuesday. Somehow, I don't think these tests are going to give me any answers (especially if the bumps are caused by an internal problem). All thoughts are appreciated.
