Pocket of air in my eye? My Right eye feels an enormous amount of pressure. it's bloodshot and hurts?

Ive been having allergy symptoms the last few days, but only when I sleep. So I'll wake up with bloodshot, productive eyes, inability to breathe and the occasional headache. this morning I awoke to a moderate amount of pressure behind both eyes.. and looking closer I noticed in my right eye the white was bulging out further than my cornea...some of the air has gone away.. but it looks almost as if im wearing a contact... the skin on my eye is loose ... and theres a bubble in the corner.. like my eyeball is swollen in that one part. HELP HELP HELP I don't know what to do. its giving me a headache as well . . .
