Since my hysterectomy with ovary removal (2/09)I've been having many breakouts with hives from mild, moderate to intense to the point of passing out and the last one I was unable to breathe. I go to the ER and Mds give me steroids and prednisone, atarax, allegra, zyrtec, zantac, solu-medrol. I'm not sure if these hives are from hormone imbalance or allergies which ive never had in my entire life up till now. Please help and advise. It seems to me if I just had my ovaries removed that it will be an imbalance, and my body seems to be going thru some kind of shock but my doctor says allergies. Please help, I feel like Im gaining weight from the prednisone. And I have never felt worse in my life. I feel like I should have lived with the discomfort of the uterine prolapse than to go thru what I am now.. Please advise
