Toenail fungus that is frustrating and painful

When you say it is worse now, what exactly do you mean? The quality of the nail? The level of discomfort? How did you lose your nails in the first place? Do you have any other symptoms of hormone imbalance - hot flashes, mood swings, rapid weight gain/loss, etc.

I lost both nails on my big toes at different times, both from a fall. The first was one I was in grade 4 or 5. The second when I was in my very early 20s.
The new toenails never really grew back properly and were always a bit ridged and thicker. Years later I realized there what was probably a nail fungus on the big toe on my right foot. After countless attempts to get it diagnosed as such, (all results from cuttings came back negative, or inconclusive), I convinced my doctor to prescribe Lamisil, but it was not to not much effect.
A couple of years ago, After moving across the country, I decided to revisit the issue. By this point, what I thought was nail fungus was occurring on the big toe of my left foot as well.
I went to a podiatrist, who concluded that there was indeed fungus under both nails. She started clipping away the nail, and removing some of the fungus every few weeks. I decided that I could continue to do this myself rather than pay her to do what I could do.
I made sure to sterilize everything before and after!
I finally just stopped because there was no improvement. It is now worse than it has ever been, with the nail on the right big toe, currently being so thick, that it is pulling in from the side to accommodate the lifting of the nail! Yuck!! While, at the moment, the pain level has subsided, at its worst, I could barely wear socks without the resulting pressure causing pain.
FYI the tips of my big toes alternate with a numbing lack of feeling, to extreme and painful sensitivity probably caused by pressure on the nail from being confined in shoes.
