Red Splotches all over body & very swollen eyes?

Okay, so im seriously desperate right now.

Over the past two days ive gotten red splotchy marks all over my body. They started off quarter size but got much bigger and have now lost the round shape. Turning into patches of red. They are itchy as hell.. The first morning i saw this i woke up to very swollen eyes. Then i noticed the red marks on my hands and arms. They started to get much bigger and very itchy. My thumb was very swollen when i went to bed.

Day two (today) Im still covered in red splotches. My face/ eyes is still swollen but now my fingers are swelling so the point of not bending now.. And i now have red dots all over my face. It started bit by bit, first it was my thumb and now its the two fingers beside it. All swollen to the point of not moving. My scalp has also been very itchy, to the point of me scratching it raw. My joints on fingers and feet are sore now too and they hurt to move. I also have to having a hard time breathing. im still able to breath, but it isnt as easy as it should be.. I also feel like barfing from time to time.

Everyone thought it might be hives from an allergic reaction, but once they spread it was obvious it wasnt. I went to emerge this morning and the dr and nurses didnt even know what it was.. They said it was either hives or a viral infection. I got a shot of benadrille and was sent home. They also told me to see my dr. So ive made an appt, but its not until tomorrow.

Does anyone have any idea what this might be ?
