HELP PLEASE. i went to the beach yesterday and used banana boat tanning oil spf8 and now i have tiny red bumps?

i have little red bumps EVERYWHERE, including my face where i didn't even apply the oil. I have blotches on my stomach, and back. On my shoulder there are little bumps, and my skin is very rough and is extremely itchy. My face as well has blotches and there are tiny tiny bumps on it. My lips are also extremely uncomfortable, my face feels tight and rough. There are tiny bumps all around my lips and throughout my face. WHAT CAN I DO ! what can i purchase to help this, and what is it ?! is it an allergic reaction to the tanning oil? Also, how long until it will go away
