I woke up this morning with my left side of my back cramping/spasming. other than drinking water, is there anything i should be doing?

Back Pain: Conservative measures in my opinion for back pain include the following: NSAIDS , muscle relaxers short term ( not soma), stretching and range of motion exercises, physical therapy, osteopathic manipulation, in some cases chiropractic care, very short term use of pain medications in the acute phase, local heat, rest for 24-48 hours, plain X-ray. No CT or MRI without neuro deficit for 6-8 weeks.
