HELP!

My friend was messing around and sprayed a lot of his inhaler on my hands and they have came out in big red blothey rashes on both of my hands and it really hurts when it's wet or getting touched. He also did it to my other friend the same and nothing has came up on his hand.
I'm really worried about it and i don't know if it can lead to something or maybe even a sign of skin cancer ?
please help.

Hi,
      There are certain allergic reactions with use or interaction with beta agonists, which are the common ingredients in inhalers. Other common side effects to beta agonists are chest tightness, irregular or fast heart rate, high blood pressure, visual changes, tremor, breathing difficulty etc. I would recommend that you consult a physician for further confirmation on this. Best.
