Anxious about hives, Zytec helps a little

Hi everyone,
I am 20 years and currently a Junior studying pre-med/biology. about 5 weeks ago as I was studying for my Organic Chemistry final, I noticed that my arms and chest/back had some small hives/red bumps. Unfortunately, ever since that day they kept coming back basically every day ranging in size etc.I also had some mild swelling of hands and feet at some point. I was diagnosed with Obsessive Compulsive Disorder about 4 years ago for disturbing thoughts and I'm pretty sure I have severe hypochondria because I always have the need to diagnose myself and I freak out from minor bodily sensations. I went to see an allergist and she confirmed that I have chronic urticaria. I have been taking Zyrtec which works most of the time but I still randomly get hives even while on it. Being the type of person that I am, I'm dying to figure out why this is happening to me and the "unknown" is my biggest enemy when it comes to symptoms. I really really really really want them to go away forever and I feel like I trapped-my parents just say that I'm spoiled and that this is not serious (which I understand that it isn't) but for some reason I cannot help but be anxious all the time because of these stupid hives.

I'm concerned about your hand and feet swelling, maybe go to your PCP
(primary care doctor) and get some blood work done.
But also go back to your doctor as it's not cleared up, Many well wishes and do
keep us posted. (and you can always try benadryl to see if that clears it up first,
but if it doesn't then get back to your doctor)
