Hi Des!
Don't be freaked out. It'll be okay, just go in and see your Dr. tomorrow. It could very well be an allergic reaction by the way you described it, however, these types of reactions tend to tone down when you remove the cause. Do not use that solution until you've discussed this with your Dr., okay?!

I really hope this helps you and good luck at the Dr.'s office!
