You mentioned your toes curling, this has beeen my main problem from the start. At first I was told it was dystonia, and that sinemet would take care of it, but best not to take sinemet too soon. So I struggled on and then started sinemet and it did nothing for my feet (big improvement in other areas, but just didn't reach my tootsies). I was sent for some electrical conductivity tests and now have a diagnosis of peripheral neuropathy, and it seeems there is no treatment for the sort that I have.
Some of the 'alternative' type treatments, although they will not cure, do help me to cope. E.g. soaking feet, tea tree oil or just a nice smelling water, then learn to massage your feet with creams, I can now coax my toes out flat-as soon as I stand to walk they cramp again but it helps with the build up of aches and it is very important to look after the condition of your skin inbetween your toes.
