Hi, welcome to Health care magic forum.
You mean to say that you are using the same things,means no new things,you are using,but you had
allergic reaction.
Some things which are not allergic to you may become allergic to you at some time. The allergic thing might be food, clothes,wool, flowers, vegetables,or any thing.The clothes may have new resigns,vegetables may be grown with some other manures,or may have remnant pesticides.
So there is a possibility of having these welts and
hives with these things.
Anxiety usually is not allergic to any one. So it may not be the cause.
I advise you to consult a physician for diagnosis and treatment.
I usually prescribe to my patient with such symptoms levocitrizine,antibiotics, montelekast,and triamcinolone40mg injection every fortnight.
Wishing for a quick and complete recovery. Thank you.
