Don't do as I did!

I have been diagnosed with tendonitis of the foot. I decided to medicate myself by putting Tiger Balm on the top of my foot by my toes. I did this before going to bed. I always have cold feet so wear bed socks that I had made a few years ago...they are very loose!
Well, my foot started to itch a bit but didn't think anything of it. In the morning I checked my foot and it was very red. Later on in the day I checked again and I have blisters at the base of my toes! Checked the very small print on the back of the tin of Tiger Balm and it says do not bandage! I presume loose bed socks constitute a bandage. It isn't that painful but itches as it heals.
