Had to see my doctor today, we had a bit of a talk and he's given me a prescription including a new medication. Both of my medications are opiate based but this one is less addictive, so rather than increasing my previous one the idea is by using two I have less chance of addiction with the same pain reduction. Otherwise he would have just increased the dose of the first one.
He's also looking into some other medications for me, as stated I can't take NSAIDs due to the horrible reaction I have to them, so he's looking into some of the antidepressant meds which can reduce pain as a side effect. But he told me he wants to be very careful giving me those as I'm not depressed and care has to be taken.
So I'll keep you updated.
