Hello~I think seeing a podiatrist is your best option, it could be a number of things, but the specialist will know exactly what to look for and the tests involved.
Do you have pain in the toe that points straight up? My big toes point straight up when I get muscle cramps in my feet. This happens periodically and is extremely painful. There area number of things that can cause this so if this is the problem you should talk to your doctor.
The skin covering your nail could be cuticle that hasn't been pushed back. A pedicure might be a good thing or a trip to the podiatrist.
Hi. For most people, their feet are not their best asset. Don't feel bad, ha. They have to like scrape layers of skin off my heels if I have a pedicure. Speaking of that, have you ever had one? Men and women both can get pedicures. They feel good to me because they soak your feet, massage lotion into them, get rid of dead skin and they might be able to get rid of the skin that is growing over your nails. I'm not sure what you mean by that. Or that your toe is pointing straight up. This is on one foot only? Does it give you any trouble walking?
