I've been struggling with pain for a very long time now. I think you should try nagestic forte ( containing cumerone), which is a natural anti-inflammatory. I bought it from chemist warehouse for about $35 and it works like cortisone. It's been a life saver for me. I take 1 tablet twice a day and noticed a massive improvement the next day in terms of long term relief. I take Targin, endone, Panadine forte and buscopan.
Good luck with the results of your CT.
