NeuroTalk Support Groups - Tarsal tunnel and herniated L5 disc related?

Hi everyone. New to the forums.

I've been struggling with chronic forefoot pain since the beginning of the year. In April, I had a positive tinel sign in both the left and right ankles. My podiatrist suspected tarsal tunnel so I had a nerve conduction test done and while not conclusive, the neurologist wrote in his report that there could well be an underlying component of tarsal tunnel.

We tried a number of things including acupuncture and physical therapy but it wasn't improving. It was suggested that I have an mri done of my spine. The mri showed that the disc is herniated at the right L5 nerve root. The orthopedist I saw to get the mri done suggested an epidural. I'm now 10 days past the injection and some of my symptoms have improved and some haven't. Specifically:

Rectal pain - gone the next day after the injection.
Vibrating sensation in my groin - 99% gone.
Numb feeling in my right foot as if asleep - 50% improvement.
Pain in the arch of my feet - 30 to 50% improvement.
Pain in the ball of my feet - little improvement although I'm walking slightly farther.
Pressure and "twitching" sensation on the inside area of both ankles - unchanged.

So this leads to several questions:

Is there anyone on these boards that had tarsal tunnel symptoms that was caused by a herniated disc?
What was done to treat it?
What are the odds that I would have bilateral tarsal tunnel and a herniated disc and they're not related?

Also, I had a complete blood count done and everything looked great, including B12 levels and my thyroid.
I'm at very low risk of exposure to toxins.

There are a lot of helpful and dedicated people on these boards.
I'd like to thank everyone in advance for their response.
Good health to all.
