Re: bil. foot pain

Hello Suresh:
If the xylocaine injection provided relief of a day, it is very suggestive or a medial calcaneal neuritis or tarsal tunnel syndrome. It is not uncommon to see a negative NCS with TTS.
A diagnostic ultrasound will also help in diagnosing plantar fasciitis if the ligament is thickened more than 3 mm. Also clinical symptomatology should correlate with diagnosing PF such as pain upon arising from a resting position, etc.
Hope this helps.
