I am suffering from sudden allergic attacks from June 2010. I have shown many dematologist (MD) and taking several medicines and steroids but not able to cure completely. Red patches comes on skin (on wrists, hands, legs, chest, back) with severe itching and when scratches, it becomes more red. Seems like blood has splashed inside the screen. I was not having any allergy symptoms before. It happened suddenly with some cluster of pimples like substance in the waist which used to itch. Now all parts of my body is filled up with small pimple like substance are are very itchy. If I treat it with cold/hot water, the itch reduces. Need immediate help for complete cure as it is hampering my work. On taking medicines, I feel like pain in chest area due to gas and it seems to pressurise from inside.
