For some months now, while awaiting a Spinal De-compression, I have been using Zomorph, slow-release morphine, plus Amytriptyline - but the pain relief effect has been diminishing. Where once I got relief almost from when I get up in the morning, I now have a most painful morning, with relief coming in slowly from mid-day onwards, until by early evening I'm really happy and real OK pain-wise.
Anyone got a clue if this is "normal" ?
I sought help from my G.P. who says that since my pain is nerve based the Zomorph is perhaps not a great solution and has removed my Amytriptyline and substituted Pregabalin, to be started slowly (I think 2 x 25mg/24hrs.), and to be built up to a higher dose eventually.
Any comments about this substitution ?
