Hi Matt, As everyone else has said - don't be embarrassed. I think you may be on the same chemo as me. I had 4 AC x 3 weekly and am now on Paclitaxol each week for 12 weeks (having No. 3 tomorrow). Interesting about the second toenails. I have the same thing but put it down to kicking a ladder (accidentally) for one and catching the other, lifting the nail, on a lounge chair. I do know that the AC can make you more susceptible to bruising so maybe it's just that those toes are in the firing line.
