1. Tight calf muscles
2. Decreased calcium or potassium
3. Tight sheets on the bed contracting toe muscles
4. Decreased magnesium
I would recommend daily stretching of the calf muscles, eating a banana or orange daily, or taking supplemental calcium. If it doesn’t resolve the cramping, see a podiatrist or family doctor.
A glass piece has gone inside my foot and the area has become red. Will a podiatrist be able to help me?
The other option, while being more radical, is to completely remove the nail, kill the root, and once it is healed, you can apply a false nail or a nail polish with nail bed adherent.
If you choose that option, there will be no functional deficit as other then cosmetics, the nails in humans serve no functional purpose.
Hope this helps.
