I was on oxycodone and hydromorph contin for over 10 years with no side effects or need to make changes ..my pain specialist was pleased that this had stabilized . I have four consecutive spinal fractures with rib issues as well . One year ago my specialist and GP both retired and the new MD is ...well I won t say more. I was expecting issues cuz of the current climate so I have some oxy ..about 30 tabs saved for busy days ..moving my 84 year old mother into a home etc. I have never had a holiday and am thinking of doing so ..but under the current Rx could not manage.. cuz I have to get horizontal every 2-3 hours .... How long will the oxy I have left ..be effective ?? It is one year old.
