LOL Arubi.. not hardly... it does it in the summer when I'm in sandals and flip flops and there is nothing touching my toes, and it does it in the winter when I'm in enclosed shoes. My dad's feet are the same way.. it's just the way our toenails grow.

Yes, I realize the problem. If a person wears ill fitting or toe restricting shoes, socks over the course of time the toes form to a certain position and it will not straighten the problem out by just a few months of sandals/flip flops.
FWIW,
Ingrown toenails are caused by impingement of the skin along the margins of the nail by the nail plate. Improper trimming of toenails, tight fitting shoes which press the toes together, hose or socks that are too tight or loose, abnormally shaped nail plate, usually caused by shoes/socks or trama to toe. Or excessively thick nail plate, usually caused by a fungus. Even the pressure of bed coverings can do this over a period of time.
A good suggestion from clem, see a Podiatrist. Chronic in-growing nails can cause deformity of the nail plate and/or surrounding soft tissues. Infection, if present, may spread to foot and leg, or into blood stream very quickly. A small benign tumor called a granuloma can form along the nail margin. Diabetics and those with poor circulation to the feet must never attempt to treat an ingrown toenail at home, consult with a podiatrist or physician immediately.
Thankfully, I have never had one, but have researched the subject because of DH's stage 2 diabetes.
Like I said FWIW to you I offer what I know.
