Hi candyrel, ingrown toenails, ouch, you poor thing :-(
Some people cut a V shape in the centre of the toe to take the pressure of the side where it is ingrowing, but I am not so sure, I think its more of an old wives tale.
Here is a link that gives you some ideas on self help, I would most definitely recommend a soak in warm water with Epsom salt added, soak for 20 minutes and then bend the soft nail out of the nail bed.

But please, please, PLEASE watch this condition, any signs of an infection or pus, you go straight to the doctor or A&E, you do not wait for even half a day, I know 4 people who had to have their big toe amputated through getting a bone infection as a result of an ingrown toenail and only one of these people was a diabetic.
I hope you get better soon.
