Could an inner thigh lift be medically necessary as an FSA eligible expense? (Photo)

I don't want to spend another TX summer covered up. The pics actually make me look pretty decent compared to how they really look and the constant, infections, I'm so embarrassed. I know insurance coverage isn't an option, but how about using my FSA? It just needs to be medically necessary per a Dr...right? Please advise...Oh, and while my arms look like crap too, they never get boils or anything like that. But these inner thigh issues are problematic. Thank you for your time.
