Sounds like you are suffering. Hope the biologics do the job. One thing, I was changed from Imraldi to Yuflyma at one time. It didn't work nearly as well and I got it changed back.
Hope your hip replacement goes according to plan.

I am 68, diagnosed at 65, previously misdiagnosed with Polymyalgia for a few years and looking back I realised I had had the condition for many years. A new consultant realised I wasn't responding to treatment so he looked more carefully.
What is THLR?

I was diagnosed with AS a few years ago. I have been on biologics (Imraldi) for about 18 months and they are brilliant. The day after the first dose I was able to get out of bed without the pain that was normally there. After a few months the aches and pains have pretty much gone except for flares.
