it may be an allergic reaction to the med's !

Yes but I just started Zanaflex 8 days ago and instantly had a sore throat burning sensation on my tongue and last night my bottom lip started burning I looked in the mirror and my bottom lip was red and swollen a little it and my chin was tomato red and swollen. So I think it's from the Zanaflex but today no symptoms and I am still taking the Zanaflex. I guess it's a mystery now as to why that happened and went away on its own. I will post a pic of it. It was the weirdest thing. I posted it under the pin board section named it burning lip and chin
