What are the methods for overcoming nail infection?

Hello doctor,

I accidentally jammed my thumb’s nail about six months ago from closing a taxi door on it. I did not treat it, as I did not realize how serious the symptoms were until five days later. It was too late to save the nail, so I let it fall off while growing a new one. After the new one grew, it had problems, such as white spots on the nail and deformation of the nail. During this time, I neglected my health because I had problems dealing with work mentally and did not attend to my thumb nail appropriately. It has been about eight months, and I believe my nails have already grown in their deformed shape. I suffer problems from it, such as not being able to properly grip things with it because the thumb is sensitive and the nail’s ending point is not like a regular nail. I am currently away from home and do not know how to treat my nail or what medication and cream to use. The problem is that the skin is soggy whenever the thumb is exposed to water. The thumb is sensitive to touch, and I cannot properly touch, grab, or grip things as before. It was my fault that I neglected this issue, and I seem to think that there is no hope of having a normal finger. I would appreciate it if you could give me detailed advice on how I can treat it and have a regular finger in touch and grip. Exposure to water makes the skin soggy; touching, grabbing, and gripping result in sensitive sensations. Kindly help.

Thank you.
