Hi Ellie, to be honest I'm not sure. My OA is certainly worse now in some area's, but whether this is due to Humira, I don't know. Probably the extra weight I've put on is having detrimental effect, particularly on my left knee (had the right one replaced two years ago) and hip.
After disc surgery last November, which is OA, I have been less mobile, so the weight has been an issue, but just started a diet.
My left wrist and thumb is so painful that the thumb feels as though it is broken some days.
After initially thinking the disc surgery had been successful, it wasn't. The nerve damage in my right arm and hand seems permanent now.
For all that, I am still delighted with the Humira results on my skin and PA. Two less things to have to cope with.
Good luck with your treatments.
