Get thee to a podiatrist asap! Trust me, they are brilliant at sorting out ingrown toenails. Which have a genetic component but are made much much worse with ill fitting footwear. Speaking as someone whose toenails started to grow into tubes during my 20s, and still do if I mistreat them. My podiatrist kept my feet functional for a long long time - far better than any doc ever did.
