A few ringworm questions.?

So I take in this stray kitten who gave me ringworm…I have a softball sized area on my leg, (I have very sensitive skin and for about a month I thought it was razor rash because it appeared the day after I shaved after months of waxing only.) So after a month I got a little spot on my side, and long story short I realized it was ringworm. I have been using the Walgreen's version of Lotriman (I dont know how to spell it), every morning four the past four days, and at night Ive been dabbing tea tree oil on it.
I read that heat can sort of incubate it so does that mean I shouldn't use my electric blanket until its cleared up? Also the medications directions say for athlete's foot apply twice a day and for ringworm apply once a day, but I dont understand this because its the same fungi, would it be ok to apply twice? Im afraid that my jeans wipe it off even when I let it dry. How long is it contagious for? I know it takes what seems like forever to heal, but surly on with the medication it dies a lot sooner than it heals?
Also is there anything I can do for the dry skin or is lotion a bad idea?
And any suggestions on some way to calm the itching? sometimes its so unbearable!
Any other care tips would be great too.
Thanks! :)
