You're better off geetting the whole nail removed rather than partials. You will always have the problem of the nail growing into the flesh.
When I had mine done, I initially oppted for partials because I'm a wuss and I hate hospitals.In the end, I succumbed to get the whole lot removed.
Eventually, I had to get them totally removed and that is the best decision I haven't made for a while. However, prepare yourself for sleepless nights when the pain and the phenol kick in.
It will be uncomfortable for the first couple of days but make sure you keep it clean and change the dressings quite often mate.
