However, if there is pain and pressure, this is caused by the build up of blood under the nail and it has nowhere to go as that is a very tight space between nail and nail bed. If the toenail isn’t totally black just use a sterilised needle to drill a hole in the nail in the centre of the black part, once you have a hole, put some pressure on the nail with your thumb and the blood should ooze out, make sure all the blood comes out, as it could block the small hole, if this happens use your needle again to unblock the hole…all the while wipe the blood away with a sterile swab.
Another way is to heat the end of a needle or paper clip, make a hole, in the nail as above and once again put pressure on the toe to get the blood out.
If the whole nail is black, instead of putting a hole in the nail, use your sterile needle and go in from the front under the nail, lift the nail, and this will relieve the pressure and the blood should ooze out the front, once again you will need to put pressure on the nail to get all the blood out
Now even though I am shuddering as I write this, I am told it is painless, it just sounds awful that’s all. If you can’t handle the thought of it, get a good friend to help ( I think mothers would be really good at this sort of thing as well)! But if there is pressure there make sure you do it, as I had a high pressured , throbbing black toe once and couldn't handle the needle bit and believe me, the pain and ordeal it took to get over it, was far worse.
The second problem you will have after your little surgical manoeuvre will be keeping infection at bay. You have exposed part of your nail bed and blood is involved, so make sure you clean the whole area with antiseptic or anti bacterial wipes and cover it with a good sterile band-aid or dressing
Ok what happens now you ask? You just sit back and wait. The nail will drop off eventually, don’t be tempted to pull it off before it is ready as it is usually joined at the nail bed or corner and can cause pain and more trouble if you rip it off before it is ready. If it is loose and driving you crazy, trim the loose bit back, or keep it covered so it doesn't keep snagging on things.
While all this is happening the new nail is growing and pushing out the old nail, and often it grow back strange, harder, and curvy…to try to prevent this happening, use Vaseline to soften it and try the filing method above, all over the nail, to try to keep it thinner and softer, and also keep the new nail trimmed.
If it is a real problem for you and painful, it’s best to see a podiatrist. They will treat the toes and show you how to trim and file them and look after them to try to prevent it happening. In severe cases you can have your toe nails removed surgically…and many professional runners opt for this treatment….ugghhhh…I’m shuddering again.
