oh, man. I had some ghost chillies plants that I grew from seeds back in 2014, and I made the horrible mistake of chopping them, then rubbing my eyes. I was in so much pain, when it settled down after a few and long hours it looked like my eyes were blistered.
Never again would I play with them bad boys haha.
apple cider vinegar is said to work. maybe give that one a try :D
