Hi Rob - welcome to the forum - but sorry you've got to have RA to be here!
I'm Sylvia, 55, and was diagnosed last May. What a rollercoaster ride those early days were, so much to take in and so many questions - if it's the same for you then do feel free to ask away. - the good news is that the drugs do really help.
My DMARDS are methatrexate and hydroxychloroquin, plus various other meds for this and that - you will quickly get an entire cocktail of drugs if you're being started on the standard Triple Therapy, which most people do.
Have you been given steroids? That's very common to get the inflammation under control quickly, although it's usually only given as a temporary fix. When I started treatment, I had a jab (in my rear!!!!) followed by 4 weeks of tablets, and that was total bliss as no pain!! It might be different for you as we are all individuals and care does vary depending on who your consultant is, but there's a lot of people on this forum and between us we have experience of most things.
Let us know how you're getting on - with very wishes - Sylvia
