What causes Hives - Stress ?

I had chronic hives for three years. My doctor claimed that I had hives that resulted from stress. I thought it was something I had eaten, but when I had hives for two weeks, I realized that it was something else. Usually, it results from an autoimmune problem. I did some research and I started cutting out all the junk foods and eating mainly whole foods such as organic fruit and vegetables. I also started juicing organic fruits and vegetables. This has helped me tremendously. I now no longer get hives and I do not have to take medication. Hope that helps.

I know that I have got the Hives after I had ate fish so I think that may of been the cause. But I have been getting these big itchy welts on my face hands ,arms, legs, back, and neck they are all spread out but they itch and I am really scared because I do not know what it is at all. They look like bug bites but there isnt anyone else in my house getting bitten so I do not know what the cause is at all. I am already in the process in maintaing my paranoia if anybody have seen all my other postings, but now this is just adding on because I am thinking of what if it's related to a illness I really do not know how I am breaking out in these welts any ideas or similar stories anyone I wish that I could show a picture on here. They look like bug bites and when I scratch them it turns to a scabe in the middle of them some of them will just keep itching. Its just so annoying if it's not one thing it's the other.

p.s how do you check for bed bugs

i developed hives as a kid for about 6 months to a year. we're not sure how it started , but think maybe i came in contact with a plant i might have been allergic to in a little wooded area between two peoples property. they eventually went away. but still to this day , maybe 17 years later , my hands get red, hot and itchy once in a great while for no reason , and my feet sometimes too , especially when i go to sleep if ive been wearing socks.
i guess my point is , it could be an allergy.

I have had red shiney hives with red borders on my neck, chest, stomach creases of my legs and arms and also on the top portion of my back. I have been to several dermatologist and they have diagnosed me with morphia scalederma. Does this go away on its own? What causes this disease and are thier other symptoms associated with this disease? I really find this disfiguring and would like to stop the lesions from appearing. Please help
