As a Podiatrist I LOVE hearing all the ideas that are out there...
DH probably not too much of a wuss as feet are highly sensitive. Things he may wish to consider are:
- always cut nail straight across, never down sides and never short
- don't cut a V in tne nail, studies say it does nada
- clean around the sides of the prone nail when NOT affected with a nail brush (old toothbrush works well) in shower to remove skin build up
- Apply liquid betadine to infected area - you can do this post a 5 minute ONLY soak in warm, NOT hot salted water and cover with a dry dressing to keep it dry and protected (not bandaids, cutiplast better)
- wear roomy or open shoes
- if recurrent consider seeing a Podiartist and having the offending section of nail removed
- consider seeing a Podiatrist for them to deal with current problem using a local anaesthetic to manage pain
- sometimes gently packing along the side of the nail with a soft foam or sliver of cotton wool can create enough of a space to stop the nail becoming ingrown
Of course, this advice comes with the caveat it depends on the situation and it does not replace the advice of a qualified health professional who has seen the toe and knows your husband. Really, the best thing is to get a GP or Podiatrist to look at it if as bad as it sounds as he may even need antibiotics, especially if he has other health problems like diabetes.
