Perhaps the disruptions of the autonomic neural and hormonal and chemical system by Parkinsonian and diabetic and other immune system disorders cause the burning feet and/or restless leg symptoms. The dystonia muswcle pains/cramps seem similar - whether located in toes, foot, calf, jaw, tongue, larnyx, pharynx, neck, shoulder, et cetera. However, the size of the hyper-tonic muscle is important to the amount of pain produced. The duration of the hyper-tension (hyper-tonia) is also important. And, the deformation (strain) caused by the unbalanced stresses in the muscles is also important in creating the level of pain felt. Unfortunately, it is also true that repetitive stressing and strains and deformations with injury weaken the structure - and sensitize the pain receptors. Adding to this is our learned expectation that the early indications of such an episode become anxiety initiators of "It's starting to cramp again!!" -- and this recognition actually dumps the hormones and neurotransmitters into the system which dys-functions (does not properly respond - one or more diseases) -- and my inability to relax inappropriately increases the tension, stress, strain, pain (cycle). ron 1936, dz PD 1984 Ronald F.
