Dermatographia Urticaria. What to do?

I still have problem of dermatographaia urticaria. I have changed 4 doctors. Once I go for homeopathy treatment, but then I switch again for allopathy as it is not curing me at all. So I go for best doctor of Derma as prescribed by my family doctor. Then the doctor prescribed me teczine levocetirizine 5 mg tablets and rabeprazole sodium and domperidone and also a blood test and actually I am not remember about test as it was 1 year ago. And in the blood report, it have disastrous values. Something is very high that causes this problem. Its value is 615+ value and my doctor said it must be 150 to control this. So after that he increase my dose for 2 months teczine levocetirizine 10 mg tablets and then after that 2 months 5 mg again and after one month when I go to doctor again he said continue these tablets and told me to do blood test again. So I did it again and this time its value is 400 around, so doctor says continue these tablets and come in between. What to do?
