Up to 30% of peripheral neuropathies, no cause is found and they are labelled 'idiopathic'. Whereas peripheral arterial disease can cause wasting and skin changes in the legs, usually only if severe is there nerve damage, I do not know how severe your peripheral artery damage is. Commonly there is a common cause such as diabetes - routine diabetes tests can miss early diabetes which can cause such a neuropathy - a glucose tolerance test or a skin biopsy looking at epidermal nerve fiber density can help the diagnosis in this case. Neuropathy in on eleg does not cause the other leg to become involved - this kind of peripheral neuropathy is because some form of body toxin or lack of nutrients is present (such as in diabetes) and this effects the longest, most peripheral nerves first hence the bilateral lower extremity involvement.
If you know you have peripheral arterial disease, then it may be advisable to have a complete vascular assessment, as other arteries may be involved also
Good luck
My dad, who has since passed away said his started in his late 40s with the same type of symptoms. By his seventies he had real difficulty walking and shooting pain in both legs.
If you excersied cycling for 6 months then suddenly the pain stopped and the only thing that changed was the clip on the pedals, then maybe it took that long for it to buildup the health benefit to your legs.
I have been walking outside and on a treadmill, but if you think that cycling is better, then I will be happy to try that. I am certainly tired of this pain and I worry that it's an indication of a more serious thing.
I've had leg pain that started summer 2004 as tingling for three days, then went away for 3 weeks, then came back as pain and has remained since. Some days are better or worse. Sitting, standing, or walking makes no difference.
I see my GP and a neurologist for migraines. The GP says the pain could be vascular and to excercise, if pain does not get better probably vascular. The neurologist says maybe nerve problems, but when he tests he can't find anything.
Each doctor sees the problem in their area of speciality. I read that in other posts here too.
I'm a 40-year-old male. I've had migraines 2 years, gallbladder sugery during that time also. I have had 2 head MRI's, in 2003 and 2004, a EEG test (normal), and a EMG of my legs(normal). MRI showed only that fluid spaces of my brain are slightly larger than in most people my age, 2nd MRI one year later showed no change from 1st MRI.
