Fingernail fungus sorry for the long post!

I’m desperate. Anyone had this problem? I have never regularly went and got my nails done. I’ve ordered stuff online from Amazon for gel nails (where you stick your hands under light) a couple months ago.

A couple months ago I was also canning some veggies out of my garden and my fingers under my fingernails started burning after the process of canning. The next day it had stopped. My thumbs started itching under my nails and it’s like under my nails were peeling. after A few weeks I noticed what looked like a fungus under my thumb nails and it has slowly spread to almost all my nails. It’s like my nails are separating from my fingers if that makes since. And under my nails get irritated especially from water.

I ordered some nail fungus meds and it seemed to go away. Now it has come Back. Im not sure what’s triggering it. It seems to get worse with painting my nails or doing the gel nails.

Can anyone help!
