I have been dealing with extreme tightness, swelling, and severe pain on my right side from my upper abdomen around to my back and hip and groin and down to my foot. So miserable. It has been over 2 years now, at least 10 family doc visits, 3 specialists, 3 MRI, 1 bonescan, 2 x-rays, EMG, pills after pills, injections, therapy... and literally have made ZERO progress on that front. Even more miserable. I have improved my daily living slightly through my own methods like building my wonderful standing desk (I posted pics of this in the "setup" thread), going through 20+ pairs of shoes to find the right ones to support me, and doing light yoga.
One of the possible causes of this chronic issue is having worked and played in the seated position, always leaning to my right side. I also haven't had full extension in my right elbow since I was a kid due to a bad dislocation and fracture (I also have ulnar nerve entrapment and they wanted to move it out of the badly damaged joint), so I literally short-arm everything on the right. After college for my job I was on the phone and PC 24/7 and obviously loved computers at home for gaming, art, reading, etc; I leaned right with my phone stuck to my ear, right to hold my mouse, right to write, and so on. One suggestion was made that I may have shortened up all the connective tissue and muscles on the right side of my body and, at one point, pulled on them very hard. They are trying to find the root of the problem but when pain is from your tits to toes, it is damn hard to tell. I also may have caused multiple injuries or one is creating the others because of imbalance. I can't remember what I did that brought it on initially, but it could have been something as simple as jumping upwards and reaching for something on a high shelf in the garage.
Moral to this story: maintain balance! Get up and move around every 10-15 minutes (even for just 5 seconds). If you can't, at least be aware of the way you sit and adjust it as much as you remember to. Your body is not meant to ever be locked in a certain position! Sedentary is bad! Just be mindful of it (I don't think you need to go to any extremes) and I think you can help yourself avoid something horrible. This especially goes for young bucks who are still really developing!
