Thanks for starting the thread OP, I wouldn't normally comment but am having a particularly shit morning so excuse any typos (sausage fingers doesn't even begin to describe it).
Another Psoriatic arthritis sufferer here (waves to @Crunchymum) and agree with so much of what's been said.
I've had joint problems since my teens but was fobbed off for a long time. Got much worse in early 40s and diagnosed with PsA. Sick leave for a year and then had to take medical retirement. I was fortunate in that had worked for NHS long enough to qualify for small pension which I am truly grateful for,but was a very hard day when I was awarded it because you have to go to a panel and it means that they basically agree that you are unlikely to ever be fit enough to work again, which takes some getting used to at rhe age of 42.
I've also had all the usual comments from people "oh yes my hip's a bit sore this morning", "yeah, haven't been able to do my 5k today", "have you tried turmeric or yoga?" - yeah am sure the NHS would be funding biologics for me if they could just shove a load of turmeric down my neck, and no I haven't tried yoga because some days getting on and off the loo is a struggle. But you normally just smile and say "right ok".
Have also been confronted on more than one occasion by some random old person in the supermarket car park when using my blue badge, having been brave or well enough to make it out of the house, to be asked why I have a blue badge and how I look "too young" to have arthritis.
Oh, and then there was the truly special day when we took my DC and her friends to a local theme park for her birthday and I took my mobility scooter. I mean you expect 8 year olds to stare a bit, but you don't expect one of the parents to actually laugh at you
.
Anyway, solidarity and love to all you fellow sufferers. Arthritis is really the gift that keeps on giving
