Did they recheck your white blood count after the antibiotics??
I know when great life changes take place I always get hives.(some are whelty, some are rashy, itch itch itch) and when it comes to my inside organs being affected by something or a foreign body being introduced I get hives. Like when I had a heart attack everytime I would have the chest pains my body gives me hives, and when they put stent into my major artery in my heart I had hives for over a year. Now, every time I get upset or have chest pains hives all over again.
I remember getting a mri once and I had the hives so bad I had to go to the hospital and cortio-steroids to make my body quit attacking itself. They shut down my immune system, cuz thats what causes them. Your body attacking itself.
Seems too me though, something greater is happening to you, it kinda worries me for you. I know sometimes the dr's mean well, but dont really understand what "you" are going thru. Seems like you are too worn down and other than some form of 'depressional state from the operation', I think something else is going on. Keep after them, I think something is wrong.
As you were writing it's like I stepped right into where you are and felt the way you are feeling, the emotional part I mean, and I just believe something is up.
Just keep at them, until you feel better I mean
much love goes out to you and your children
god bless you
