Hi Robert,
Did you mean that your doctor gave you prednisone 60mg? I can't find anything out about anything called predicore when I google that name.
Zaldiare is a good pain relief medication.
Not everyone gets relief of nerve pain with neurontin.
Have you been taking prednisone for the nerve pain for the past 2 months? That's an extremely long time to be taking high doses of prednisone. It is usually given in a medrol pack of prednisone which is a decreasing dose over a 7 day period.
I've never heard of giving prednisone for the length of time you indicate you are taking it for nerve pain.
It also sounds like you have nerve compression in your L4/L5 vertebrae area, but you have not said anything about the specifics of your MRI and what the doctor told you.
It sounds like you should get another opinion from a well qualified spinal surgeon as the treatment you are getting really doesn't sound up to par.
It also sounds like you are in dire need of a good physical therapy program to strengthen your core muscles, learn proper exercises to do to keep them strong and how to do them properly.
You should never just start doing exercises on your own because if you do the wrong ones, or do them incorrectly, you will cause serious injury to your spine.
