I'd try the tennis ball method and see if it works. Another option would be to go to a massage therapist and request trigger point or similar treatment. At least one hour, maybe 1 1/2 to make sure you can target the problem and get good advice.
The internist is right...the sciatica's source is in between those two discs. Although I work extremely closely with my drs., I bought an Atlas of Anatomy (mine is Grant's) to do my follow-up research. Plus, a Pill Book (can find at pharmacies anywhere) has proven helpful.
Woof.
