Yes, I had it in my mouth also. Regardless, it was not H,F&M. From my own research on the internet, it didn't look like that, though it certainly hit all of the same sites on my body. Completely different looking rash and blister size. This was further satisfied by the skin doctor. He said it was just a normal virus and my further research in that regard, bore it out. The mystery remains as to where it was contracted.
As I've said before, normal virus or not, I hope I never experience anything like that again.
