Can peripheal neuropathy make legs ache? and make an ulcer? if so how can this all be healed?

Yes and yes: The cause of neuropathy needs to be treated. It is not feasible to provide a meaningful opinion without examining you and may be doing some tests. It would be prudent to see your doctor at the earliest. Wish you good health!

Neuropathy can frequently be painful, and advanced peripheral nerve disease could cause lack of sensation and secondary pressure sores and ulcers. If this describes you, see a neurologist and start an evaluation regarding causation, so treatment can be precise.
