What Causes Pain In Right Foot Causing Difficulty In Walking?
Agree with your podiatrist, Sounds like a Spur
Detailed Answer:
Hi XXXXXXX Thanks for coming to HealthCareMagic.
First off I agree with your Podiatrist. This is not due to the disc issue or any kind of nerve inflammation. When a nerve gets impinged you get pain that travels all the way along the course of the nerve. Your pain seems more localized in the midfoot. I believe (from the description you have given) that you are suffering from a Calcaneal Spur. This is a bony outgrowth from the bones of the foot that is causing inflammation.
The recommendations for such a problem are pretty simple. Specialized Orthotic shoes (or at least specialized insoles for your existing shoes) are helpful for keeping the pressure off of your midsole. Pain killers like Brufen for when the pain is very bad. If the problem lasts more than a few months (and yours has lasted 5 YEARS!) then you need to look at 2 options.
1) Steroid injections directly into the Midsole to bring inflammation down.
2) Surgery to remove the spur.
X-rays of the foot will help determine if this theory is correct or not.
As far as a good Podiatrist.. unfortunately the field is very limited in the country. Your best bet is to go to HOSMAT (Bangalore), you will find someone who has seen this before over there.
I hope this helps. Take Care.
