Interesting article Jo.
I've had tons of hip pain but I don't know the cause and nobody will investigate. Is it arthritis? Is it a lack of blood supply or is it related to ligaments and tendons? I've always walked for 30-60 minutes per day and sometimes my hips ache and sometimes they don't. Sometimes when I walk, I can feel a thud going through my hips and sometimes they seem to be looser.
I've tried exercising and resting and I think exercise does help more. Not sure how I get to diagnose which of the above 3 are causing it or whether there is another cause.
I've had a little hip pain on and off for many years, but it's only since the LSSc diagnosis that it seems to have got really bad.
I had to give up cycling in 2000 mainly because of painful hips and did extra walking to help make up for it.
Exercise and activity have always been important in my book and I do as much as I can. I wish I could do water based exercise as it's known to be beneficial, but Raynaud's makes swimming unbearable.
