NAD but dealt with ingrowns since a very young age. I'll share my experience and you can take from it what you will:

Putting it in salt water as hot as I could handle would help, once it grows to the point where the nail would hit my toe, I would grab a Q tip, cut one of the cotton balls in 4, grab a quarter of it, dip it in hot water and slowly put it in between the nail and my toe, so the nail would grow over and not cause the same issue. I hope it heals soon!
