hip problem , faciliation at the L4/5 , pelvic rotation ???

Hi my name's Jo. I'm a 22yr old female.

I have had pain in my right hip for over 4 years but it has been getting a lot worse lately.

I went to see my doctors back in February 2006 with this problem, but my hip was very clicky and it sometimes hurt a little. The locum doctor there couldn't say there was anything wrong, but it could be a connective tissue disorder as the muscles around my right hip were very tight. He said for me to get some exercise, but I'm practically on my feet most of the time at work, for around 6-7 hours if I miss out the breaks and times when I do sit down, and I'm petite and very slim for my age, so it can't be that.

Anyway, I carried on with things, but in February this year, I was on holiday with my partner in London, and we were walking around. I suddenly felt a sharp stabbing pain in my right abdominal area and right hip area, right over the crest. I just thought it was a normal stitch, but it was making me feel stiff when I was walking and so I had to stop.
This happened around the 27th/28th of February. I took note of this, and through all of the 4 months the pain around my hip and tummy area HAS come back and has been hassling me a lot.
I was starting to wonder if it could be my menstrual cycle as I start around the 4th-8th. But I didn't want to jump to any conclusions so I just let it be.

One morning in May this year, my right hip had been hurting a lot more, and the pain was so severe it woke me up an hour before I had to get up. I got up because I was in so much pain, went to stand, and my right leg couldn't even support my weight, and it actually gave way underneath me. I was also feeling very stiff. I made an appointment that day to see a doctor, who was a locum doctor also, and he made no diagnosis as he seemed to think everything was ok. Even though he said everything seemed normal, he referred me to an osteopath, but because they weren't on the NHS, I had to pay to go private.
I was in so much pain and I just wanted it sorted out, so I went with a practise which was just up the road from where I lived.

I saw an osteopath that day, which was quite good, and he became immediately aware that my spine had been extended. I wasn't sure what he meant, but he carried on to say that I was hypermobile and because of my slim build, was very bendy.
He did a range of palpation techniques on me and suggested I take up Pilates to help strengthen my back.

For 2 months I took up Pilates privately and I saw the osteopath every 2 weeks, but my hip was still causing me problems.

2 weeks ago I saw a female osteopath and she had a feel around where I said the pain was felt. She told me that my pelvis was quite twisted.
That was when I started to panic, but she simply said she can only treat me so much for it, but if I'm in any more pain and if she seems to think it isn't musculoskeletal at all, then I should go back to my doctor.

She sent a letter to my doctors and sent a copy to me. I just wondered if what I have is anything specific because there are so many big words in it!

She writes that " a general hypermobility was noted with faciliation at the L4/5 level seen. A pelvic rotation (anterior on the right) was observed with hypertonia through the right psoas muscle palpated."

Does anyone know what this means and is it anything I should be really worried about? I'm very confused by what she wrote and I want to know if anyone out there has any idea what it is. Please help!!

Thanks

Jo
