Ingrown Toenail Dangers
First of all, unless you are in fact a doctor (in medicine, Professor), do not attempt a DIY home surgery. No draining anything with needles or pulling apart the nail with tools from your any-thing-but-sterile shed. You'll just butcher your toe and exacerbate the injury. You could also very easily create an infection.
If you have diabetes, circulatory problems, AIDS, or are undergoing chemotherapy, getting rid of ingrown toenails is a very serious matter. These conditions undermine the healing process, turning a normally innocuous injury into something more. See your doctor as soon as possible.
How to Prevent Ingrown Toenails
Trim toenails correctly. While you need not grow talons, most people hack off far too much nail. Doctors recommend clipping toenails straight across without rounding the edges. Lengthwise, nails should be even with the tips of toes. Sacrifice a little vanity for practicality and you may never have to get rid of ingrown toenails again.
Wear comfortable footwear. High heels, cowboy boots, pointy shoes, and ill-fitting footwear can all cause ingrown toenails. Shoes should conform to your foot but give your toes a little freedom. If the overenthusiastic salespeople can't help you at the local shopping venues, talk to your doctor. You may also want to take a look at the website for the American Podiatric Medical Association, which sports recommendations for footwear of all kinds.
Protect your feet. If your occupation or leisure activities may lead to toe crushing, take proper precautions. Introduce a nice pair of steel-toed boots to your shoe closet.
