I have pain almost constant under the toenail on my.left foot, under the toenail on only the next to smallest toe. I have seen three podiatrist about it in past 3 years, and discussed with two orthopedic surgeons. None would remove the nail to see what is wrong. One was going to but insurance (Aetna) would not.okay an MRI. So, no one did anything. I'm now in 3rd year + suffering pain from this. What can I do. At times, I feel need to have that toe amputated.
