See below: Current stressors like your surgery, impaired sleep due to pain, possible reduced workload or other changes in your life can bring on anxiety. You may also have had a preexisting anxiety condition that has broken through with tolerance to the opioid med. You may try other tx like cognitive behavioral therapy, exercise, stretch or manual tx: chiropractic care. Check w/ your Dr. about the symptoms.
