strange welts on my face and neck?

I have these welts on the side of my face and neck. I cant think of anything that would cause this only on one side of my face. Im allergic to all kinds of stuff outside like pollen and mold, and also mosqitos, dogs, cats, and rabbits. im probably allergic to more than that, and just dont know it. I also hav asthma. Im around dogs all the time, but I have never actually gotten welts or anything, only sneezing and stuff like that. I considered mosquito bites, but all of the welts are on one side of my face and all over the side of my neck. And I rarely get bitten on the face by mosquitos anyway. I've had the welts since friday, and I have no changed any face wash or soaps or anything. Not sure if anyone can help me, but im kinda desperate. Ill go to the doctor monday, but I dont think theyll be able to know where the welts are coming from if its just . An allergic reaction. Has anyone else had symtpoms similar to this before? I have about 8 welts on the side of my face, neck, and one on my chin. Thx

You were right, it was itching. It was actually a food allergy. I'm allergic to hummus.. I realized because I had gone about 3 days without eating it, and the welts went away. After eating it a few days later, I got hives all over my hand. Still not sure why it was on one side of my body only. Anyway, I havent eaten hummus since, and i've been fine. Guess thats just another allergy to add to my list. Thanks so much for your help!

Hello and hope you are doing well.

If there is pain, then the rash could be due to herpes. Here the rash is limited to the dermatome the nerve supplies. If there is itching, then it could be an allergic reaction. The rash could be due to contact dermatitis, that is exposure to an irritant like a chemical or metal or anything you are allergic to, it can cause rash. It could also be due to fungal or bacterial infections. But to exactly pinpoint the pathology you will need to consult your primary care physician who will examine you and may ask for blood tests. If the need arises he may refer you to a dermatologist.

Hope this helped and do keep us posted.
