I’ve gone in and out of a sort of vortex of doom, especially when first diagnosed. However I’m not as far down the path as you as I’ve just started my 2nd biologic, when the first one failed after 11 months of using it. And I’m less than 4 years diagnosed.
We’re told here in the UK to give biologics 3 to 6 months to see if they do anything and then told most don’t get up to full efficiency till you’ve been on them a year. So going through 7 of them in 3 years seems sort of super quick. And it would then feel extremely odd to me to be told 'actually it’s ‘probably’ osteoarthritis at the end of all that. That would send me metaphorically ‘running’ to another rheumy very quickly, frankly. Are you thinking of doing that as well as the pain management stuff? I would be. Very much so.
For me dealing with the loss of ability and capability talking therapy helped enormously. I resisted the anti-depressants though. But if I had gone through so many biologics as you have without some relief, I would certainly be extremely concerned emotionally. And exceptionally fed up and very depressed too.
Get a second rheumy opinion please. From a rheumy who is really excited about PsA, whose career is based on PsA. And then see. Such a specialist should be also properly capable of distinguishing between OA and PsA too instead of talking about things ‘probably’ one or the other. You could have both, or one or the other but wouldn’t it be useful to know more coherently what was what? And most certainly give the pain management thing a decent go. As @Sybil said ‘structured, targeted training’ is always a good thing.
And in the meantime have an endless supply of cyber hugs from me.
