Advice needed please....?

I am from the UK. My wife has had a back operation about 12 years ago where its all gone wrong.

Over the 12 years she has had pain in her lower back. We have tried a variety of treatments but nothing is effective in the long run.

My wife is now on strong medication. She has been taking the following drugs for a few years.

a) Oral Morph - when required
b) Zoromorph - twice a day
c) Diclofenic suspository - when required
d) Pragabalin - twice a day

My wife is only 37 and these drugs, i feel are harming her rather than helping her.

Before my wife started to take pragabalin she was a size 10, now she is a size 18 - 20.

Pragabalin is known to make you put on weight.

The doctors have now said that they will slowly take her off the progabalin and replace that drug with Duloxetine.

This new drug is cauising her rto be very sleepy, loss of cordination and more....

My question is..... can anyone recommend a drug that has lower side effects that deals with the pain issue?

I forgot to mention, my wife has an issue with the nerves in her lower back which started from her operation.

Also, we are from the UK, so the names of the drugs may be different abroad.


Thank you for your help.
