Maybe a hydrocortisone cream or lotion? Neutrogena makes a medicated lotion. I heard Gold Bond is good.
I had bad itching for a long time then had red hives all over for 3 months.
I hope it is just dry skin. I have Hashimoto's Thyroiditis which can cause hives.
Maybe you have a hormone that's off or something going on with your immune system...or it could just be really dry skin :)
If hydrocortisone and medicated creams don't work I would see a dermatologist.
