Mr Tsitskaris describes the common reasons people book to see him at The London Independent Hospital for a private consultation:
"When somebody comes to see me, the most common reason is that they have been troubled by gradually deteriorating, persistent pain in their groin. They're often quite surprised when I tell them that this is probably caused by a problem with their hip, as they think - as many people do - that their hip is on the outside of their leg. However, your hip joint is actually in the groin area.
"On occasions, people will have already tried non-operative treatments before they come to see me. For example, they may have tried pain relief medication or to lose weight, physiotherapy or other conditioning exercises.
"These will often have helped them a bit, but then gradually they get more persistent and deteriorating pain, even at rest."
The National Joint Registry suggests that most people with hip pain will be in an older age group, around 70-80 years old, but Mr Tsitskaris' experience is of seeing people younger than this UK average. He believes this is probably due to the younger population being more prevalent in London. And as he points out, arthritis can occur in younger people too.
If you are concerned about a problem with your hip that is not settling or easing over time, or that is causing you significant problems with your daily activities, it is best to see a doctor for assessment and advice at an earlier stage.
It may be found that no treatment is needed, and this can be reassuring to know. If it is found that treatment would be appropriate, this can be arranged for you without delay so that you can get back to better, easier movement sooner.
