Most of us take them for granted - after all, they aren't alive, and you can break one without it hurting. I'm talking, of course, about your nails. But you'd be surprised at how many messages they send out about your general health.
Fungal nail infections
Thrush - whether it's athlete's foot, vaginal thrush or that sore, itchy rash in your groin or under your breasts - very commonly affects your skin. Thrush is caused by a fungal infection, from yeasts which normally live harmlessly on all our skins. But if a fungus gets into your nails, it can be difficult to get rid of. The main symptoms are thickened, flaky, discoloured nails - often your toenails.
If your doctor thinks a fungus may be to blame, he or she will probably send a clipping from your nail to the laboratory. Because creams don't work for fungal nail infections, you may need to take a tablet a day for three to six months to get rid of the infection. Fortunately, it may be unsightly but it's harmless.
Little pits in your nails are common. Very occasionally, they can be a sign of a condition called psoriasis. We usually think of psoriasis as a skin condition which causes red patches - but in a few people, the main symptom is joint pain. It's worth talking to your GP if you have persistent or unsightly pits in your nails.
No, not partying late into the night, but swelling of the end portion of the fingers, along with curving over of the fingernails. It's sometimes described as 'drumstick fingers' because of the swelling. Usually linked to lung or heart conditions, along with inflammatory bowel diseases like Crohn's and ulcerative colitis, or primary biliary cirrhosis, it definitely needs checking out.
I've lost count of the number of patients who've told me they're short of calcium because they have white spots or lines on their nails! In fact, it's nothing to do with this. It's probably simple bashes and bangs to your nails.
The best thing you can do is to stop worrying - and maybe protect your nails to prevent it happening again. It's very common in gardeners and DIY enthusiasts. The spots or lines will gradually grow out to the ends of your nails and then disappear.
Ingrowing toenails - you can prevent them!
Ingrowing toenails usually affect the side of your big toe. The nail starts to grow into the flesh at the side of your nail, and can cause a nasty infection. This can often be treated with antibiotic tablets. Occasionally, it keeps coming back, and you may need a minor operation to remove part or your entire toenail.
Fortunately, a few simple steps can keep ingrowing toenails at bay. Firstly, don't EVER cut your toenails down at the sides - always cut them straight across, leaving them longer at the sides. Secondly, make sure your shoes have plenty of room at the front, so your toes aren't squashed. Thirdly, wear open-toed sandals or comfy slippers at home, to avoid pressure on your toes. These measures will also cut your risk of bunions! Finally, if you find it hard to cut your own toenails, talk to your GP about a referral to the local chiropody or toenail cutting service.
