Sounds like you may also have a pinched nerve.  Sciatica or some such thing.
I'd call the doc.  We can't tell you what to do about meds.  I do know that
with Gabapentin it has a very, very short half life so it's out of your
system very quickly.  That may be why the pain felt worse this morning.  It
could also be neuropathy and the some other nerve irration on top of it.  As
always, any serious pain should be discussed with the doc.

Bless you again. I looked up the symptoms of Sciatica and I'm
experiencing everyone of them and nothing else,

I think maybe I should push away from the chair and walk more.

Understanding sciatica pain
For some people, the pain from sciatica can be severe and
debilitating. For others, the pain from sciatica might be infrequent
and irritating, but has the potential to get worse. Usually, sciatica
only affects one side of the lower body, and the pain often radiates
from the lower back all the way through the back of the thigh and down
through the leg. Depending on where the sciatic nerve is affected, the
pain may also radiate to the foot or toes.

One or more of the following sensations may occur as a result of
sciatica:

   *

     Pain in the rear or leg that is worse when sitting
   *

     Burning or tingling down the leg
   *

     Weakness, numbness or difficulty moving the leg or foot
   *

     A constant pain on one side of the rear
   *

     A shooting pain that makes it difficult to stand up

While sciatica can be very painful, it is rare that permanent nerve
damage (tissue damage) will result. Most sciatica pain syndromes
result from inflammation and will get better within two weeks to a few
months. Also, because the spinal cord is not present in the lower
(lumbar) spine, a herniated disc in this area of the anatomy does not
present a danger of paralysis.

Symptoms that may constitute a medical emergency include progressive
weakness in the legs or bladder/bowel

Peace :-)

Find a doctor who can distinguish diabetic neuropathy from sciatica!
You've been put on a very powerful drug that may have serious side
effects which is NOT recommended for sciatica. A good doctor should be
easily able to distinguish between the two.

According to my endocrinologist diabetic neuropathy tends to be
symmetrical. Sciatica affects one leg (or in my case where I have two
discs each affecting a different leg, different portions of each leg.)

I have found that plain old 325 mg Tylenol is the best painkiller for
the sciatic pain.  But go easy on pain killers as all of them are hard
on your kidneys and liver.

If you can, get up and start some gentle walking. Sitting for 12 hours
will end up crippling you.  I also find that certain postures are more
damaging than others. For example, I can type happily for hours without
making my back worse, but if I am debugging code by 3 hours in I'm in
pain. I love debugging code, so it is not psychological. I assume I'm
holding my body differently when I do it.

You should also look into how your chair is set up. It might be too high
or two low. Getting that right puts less stress on your lower back.
I had to buy a lumbar pillow for my car and a small pillow to fill in
the seat cushion as the bucket-shaped seat is a guaranteed pain-maker.

When I had a back injury and couldn't sit down for long I got my
office to give me an architect's drawing board I could use as a
stand-up desk.
