Thanks Robert. Next to a good, long massage by a very experienced masseuse, muscle relaxers would be the best drug to use.

Spasms are acute and very painful, but usually not chronic. Using a powerful pain killer like oxycodone really wouldn't help much. And someone posted about using a benzo, anti-anxiety drug, but I don't see how that would help.

Probably better to use a topical gel like Voltaren or Aspercreme I think.
