I've been struggling with a lot of shit my body has been throwing at me over the past few years... I can't do things I want/need, because my wrists, elbows, feet, back, etc. are all messed up. After about 3 years, 8 doctors, and 2 physical therapists... someone finally can diagnose me. I've got a genetic disorder called MASS Phenotype, which basically is just an array of different problems stemming from a lack of connective tissue. I'm a skinny guy, I always have been. Right now I'm 21 years old, 6'3", and I'm right around 160 pounds. I was informed that it might be helpful to try and gain some weight, and try to work up some muscle around my joints to reduce the constant pain. I'd love to give this a try, but I'm one of those guys that can eat anything and not gain a pound. I've been looking on the internet today for supplements, powders, etc. Another stepping stone I've gotta get over is that I'm a pretty picky eater, which is terrible considering my diet plays a big role in how well this turns out. Any suggestions or insight?
