I’m sorry you are both going through this, it’s really difficult. I’ve had RA for 12 years and getting the right treatment, and no pain takes a long time for most people.
A lucky few will get the right drugs, that really work for them first time but for most of us, it’s trial and error. Each drug needs about 6 months minimum to see if it is effective, so it’s a slow and difficult process.
However, if he’s still in pain then he needs to be more proactive and demand better pain relief, you have to push, but RA isn’t the end. It’s more of a semi colon until the treatment is found. Be that DMARDs or biologics.
He can help himself by taking warm baths, resting before and after big days out, managing his expectations as well.
It’s an adjustment for life but life is definitely still possible. There are a few really good help sites like Versus Arthritis which have a lot of information on.
Mostly it’s about staying as positive as he can, and pacing himself. Pushing for better pain management and not just giving up.
I won’t lie, it’s a horrible disease but there is hope and some fantastic medicine out there. It just takes time, and patience which is tough when we all want an instant miracle x
