Tarsal Tunnel Syndrome
'In this disorder, compression of the posterior tibial nerve at the ankle results in severe pain leading to disability and reduced ambulation. Presenting symptoms include burning and discomfot, which may be severe and usually radiate to the toes. Pain increases upon ambulation and is relived by rest. The condition may be diagnosed by Tinel's sign, distal dingling produced by tapping on the nerve at the site of compression.'
So, I guess Post Tib Tendonitis and compression of the Post Tib nerve could be inter-related? Or maybe just the same location?
