I’ve had injections and loratadine tablets, but it still comes back afterwards. I’ve been to a skin doctor and the doctor gave me a prescription, and I’m currently taking Chinese medicine. Do I have to continue to take Chinese medicine? Will it come back in the future? I have been abstaining from eating for a long time. The actual fact is that you will be able to get a lot more than just a couple of months to get a lot more than just a couple of months.

I suspect it’s because I ate a beer-battered duck. Or is it because you can’t blow the wind? Wang Haibin, Department of Dermatology, Jiangxi Specialist Hospital for Skin Diseases: It is important to find the cause of chronic urticaria. You can record each of the foods you eat every day and compare them to the days you develop them, so that you can find out most of the ingested allergens. If it’s convenient, come to the hospital for an allergen test and have your doctor analyze it for you.
