After searching and finding some useful info in this forum (and General Cycling), I would like to ask if anyone here has a similar, more specific issue.

I have never been obese, current BMI is 27, and only recently (a couple years) have been showing symptoms of Peripheral Neuropathy in my toes and plantar fascia. At first I thought it was athletes foot, but then quickly jumped to the conclusion that it was plantar fasciatis. I have had flatter feet my whole life, but my feet only recently started bothering me. I have tried orthotics, while they have supported my posture, they have not helped my feet at all. I have no other symptoms of Type 2 diabetes, and to my knowledge, no one else in my family has/had this disease. My feet have good and bad days, but I cannot determine what may cause this fluctuation as my diet and exercise regimen are fairly consistent.

I have been to two foot doctors and my GP for advice, but no one seems to have the answer. I'm fairly certain that based on this symptom that I may be early-onset, so I'll be going to the doc for a specific test.

I'm wondering if anyone else has or had this condition, and if it has improved with their cycling regimen as well as (of course) diet. Thanks in advance for any feedback.

Peripheral Neuropathy can be symptomatic of many serious diseases (DM, MS etc.) or it can be that your shoes are too tight.

Sounds like you are doing a lot of self diagnosing. You won't find a diagnosis on Bike Forums.

If your practitioner is shrugging his shoulders while your symptoms persist and cause you discomfort, find another one.

Thanks - I posted here to see if anyone else in my community had similar results with a similar regimen. I know you're not (all) doctors, just exploring possibilities. My shoes are not too tight (I have five pairs of varying brands and I make sure to try them on before buying).

In your O/P I did not read that your are diabetic, but symptoms of P.N. can start before diabetes.
I would get a blood gluecose test done/ full blood-work up as well as a fasting type blood-work up done.
Sometimes P.N. presents itself long before a diagnosis of diabetes or other diseases. BMI is significant in my mind as the more weight you carry the more stress and pain it causes in your feet as well as your lower joints, also there is progression with neuropathy.

Also P.N. can cause other problems such as arthritis, skin problems and foot-drop.

personally I would get a complete physical/blood-work-up/ chest x-ray/ or even a C.T scan if possible also see a neurologist for an EMG study for nerve damage..
P.N can be related too many different diseases/ disorders.

I suffer from sensory neuropathy from herbicide/pesticide poisioning and it can really be quite excruiating in regards too on going daily pain. I do take pain meds which helps but not always successful in stopping the pain.
I find my road riding/bicycle riding does wonders as it does help to circulate more blood to the outer toe/foot digits which is important as the nerve damage can also constrict blood flow and induce a higher level and more dangerous problems. to your feet as well as problems with callouses and hammer toes.

Furthermore I would suggest a weight lifting routine because if you do suffer from P.N. it can and will effect your muscle and joints over a matter of time.

excellent post.
I would definitely see a Dr. if I was the OP. Nueropathy in any of its many forms is no joke, and there are treatments that can help.
