What causes these dreadful foot itches that just don't respond to normal scratching, that seem to be really deep? I have one now and it is driving me mad.
It can be caused by diabetes affecting the nerves in the feet. I have the same feelings on occasions, as well as both increased sensation and loss of sensation. It seems worse at night and can often keep me awake. There is a cream and tablets available to stop the nerves playing up but they would both normally be used when or if the condition worsens.
Agree with mrburden that it could be caused by the nerves in your feet, get this checked-out by your GP and hopefully they can prescribe something to stop this sensation.
