Hi, Ellie. I wish people would stop telling others their hips or legs or other body parts are not exactly the same length or position.
It just gives us more to worry about. I hope you can ignore it. If you are in pain, it is most likely from TMS, some repressed emotion or a perfectionist or goodist person. Or you're just worried about something... finances, relationships, work, etc.
When we worry our mind sends us pain. We can end the pain by believing it is TMS and not structural. Everyone gets pain of one kind or another during their life, and most of us get headaches. It's important to learn relaxation techniques... mindfulness (living in the present moment), meditation, deep breathing, thinking positive.
Don't pay any attention to nay-sayers and criticizers. I had some of those and stopped seeing them and felt better. I spend my time with happy, positive people.
