I've been two years ago with my dodgy hip. (And posted on here before about it) I told them how it behaves - normal most of the time then out of the blue if I stood up wrong I would be unable to put weight on my leg or to lift if from the ground and to try would be agony. If I stood and twisted wrong then I'd get a stabbing pain.
I was prodded and poked, given a blood test and an x ray and was told (after they lost, then found my results) that there was nothing wrong.
2 years on and I've learned to live with it as it only happened once every couple of months.
In the last month or so I've noticed that the same hip joint feels really tight when walking after I've been sitting for a while. I've had a couple of occasions when I've stood wrong and been unable to move until I've sat down and stood up again- once at work in front of my class of y4s where you cannot swear with the pain.
Final straw was Friday. Out with friends, nipped off to the loo and pegged it up the stairs quickly so as not to keep them waiting. Half way up the stairs my leg completely gave out with a stab of pain and I crumpled down. Thank God I was going upstairs and not down at the time. Each step was painful until I made it to a seat where I could sit and stand again. THen it was fine.
If nothing has shown up before, am I going to feel like a fool wasting their time??
