Hi Jacqie ~ Very happy about your experience with Methadone. Glad it is working for you and giving you relief to be active and enjoy your life!
Jaqui, methadone is an excellent medication for pain for a variety of reasons, and helped me to manage pain of a long-term spine disorder for 12 years.
There is research that links methadone to a particular cardiac problem. The cause is poorly understood, but to minimize risk, my doctor has ordered a 12-lead ekg with my annual physical (when I am using methadone), since i am also in my 60s. So far, I remain without cardiac symptoms.
