Left side of body hurts

[LuciferRising]

My left ankle, knee, wrist, and thumb all hurt. The muscles are also tight on that side to the extent that I can barely do some yoga poses that I can do easily on my right. My left eye is also terribly dry and itchy all the time.

I plan to get a non-emergency GP appointment, but is there anything that could cause pain on one side? Peri? I have lupus, rheumatoid and osteo arthritis in the family.

I am 46. I do martial arts and yoga but am starting to wear braces on each joint. I don't do these activities enough for them to cause issues - 3 times a week in total and have taken a break.

I had something like this on my left side and nobody could tell me why, but I came across Neal Hallinan on YouTube who does postural restoration.
It's about how our right side is naturally dominant and we can over time become too dominant on that side.
He has loads of videos. It's fascinating.

I did see a sports therapist for a knee issue last year and they mentioned one of my legs was slightly longer than the other - can't remember which one and no medical professional has ever noted it. I do wonder whether that could cause an issue, and whether it is indeed true that I have it .

Neal Hallinan mentions one leg longer than the other in some of his videos. Apparently it's common and is to do with 'posture' but in a neurosensory way - your perception of the ground under your feet for example. It seems many of us don't feel our left heel on the ground which affects everything further up.
