You need to clip it... that is the only thing that would help me. I get ingrown toenails. and I am very diligent in keeping it low so that it does not become a problem. If for any reason it does become a problem - I dig in there and clip the side (gross I know)... but if you don't it might become infected.
Go to your closest drugstore and get some Outgrow. It's in a brown bottle with a yellow label with green writing. Put it on the ingrown nail three times a day and it will take care of the problem. Easy!
Re: ingrown finger nail?? ouch! help!
Is it infected? I'd start by soaking in warm salt water 3x/day.
