i developed RSi in my early teens from working as a meatpacker/slave labor for narcissistic parents. now, im my 50s, i just limp along and have a good staff under me at The Yob. one ting i can recommend to you 2, actually is 6000mg of MSM daily (buy it on amazon) it helps greatly over time wit inflammation. and get yourself a WP900 black and decker on Amazon and use it daily, at least twice when you are actively working. keeping the muscles loose and fluid at all times is the goal. you can find vids about the wp900 on youtube. https://www.amazon.com/DECKER-6-Inch-Random-Polisher-Renewed/dp/B07KXCLQXS/ref=sr\_1\_3?crid=2QOS5EXZITI4O&dchild=1&keywords=wp900+black+and+decker&qid=1634338217&sprefix=wp900%2Caps%2C204&sr=8-3
they don't ever explain this, not really. but almost all muscular pain comes from 2 things. the primary one is a lack of oxygenated blood to the cells. no oxygen, you get the entire area screaming in pain. and with RSI, you get large areas doing just that. it can be excruciating. other is the tendon injuries. they will scream in pain, but they don't have a real network of capillaries feeding them blood. so they can just go on screaming for months or years depending on the severity. i had both. and had no real treatment options as i knew nothing .the only thing on the internet was the sorehand board . but now you can get yourself some real treatment tools for just a couple of hundred $ the first is the armaid at armaid.com. the second is a WP900 from amazon. https://www.amazon.com/DECKER-6-Inch-Random-Polisher-Renewed/dp/B07KXCLQXS/ref=sr_1_1?dchild=1&keywords=wp900+black&qid=1621356031&sr=8-1 get both of them and learn to rest your hands. you will recover but it will be so slow that at the beginning, you do not compare how you were a week ago, you go back 3 months and make a comparison. be strong. be patient.
