the tip of my right index finger was pale grey - whitish, it had wrinkles that at the bottom of the wrinkle were blood red. It's gone away now, it's actually when the skin gets too moist, it traps the moisture under the band aid, which is tight against your skin. This happened after I went to bed at 3 after 9 hours of c.o.d., and forgot to change my band aid. Long story short, weirdest pins and needles ever.
