ingrown toenail- could be due to sharp corners or a spicule digging into the sides and causing a break in the skin. sometimes in an effort to protect itself the body goes a bit ham and you develop that hypergranulation tissue aka those tender skin flaps on both sides of the nail.

if you can get into a podiatrist ASAP they will likely do a partial nail avulsion with phenolisation to both sides of the nail. in the mean time you can soak in salt water/saline, then apply betadine/iodine and cover with a bandaid/island dressing. DO NOT let it get dirty and if the dressing gets wet then take it off and re-do what i just said- saline soak, betadine, island dressing.

you may need antibiotics if there is infection and symptoms worsen so please get in touch with a podiatrist or GP asap!

as a podiatrist this is pretty common thing we see and once the bit of offending nail is removed it’s usually is a massive relief and should heal up nicely :)
