My wife is a 79 year old white female with congenital back problems and multiple problems with her shoulders, legs, knees, hands all associated with arthritis. She has had several surgeries over the years, shoulder replacement, knee surgery,and back surgery. She is presently being prescribed Hydrocodone APAP-10/500 for pain. She has been on this dosage for about 2 years. It was marginally effective when she began taking the medicine and now is ineffective. Her doctor has been very reluctant to consider an increase in her medication. Should I consider making a change in doctors?
