I have been on Medifast for 2 months. My hair texture has changed, my left foot is swollen and chest and back are itchy and bumpy, also turning 50. I have lost 15lbs so my BMI is 21.1 a healthy weight. I also may have psorisis, which I had once diagnosed 10 yrs ago for a small spot on my shin, have not had it since. Upper forehead area gets dry patches, then I wet my head and it easily peels off. A few hours later it s itchy and I have to scratch & pick it off, endless cycle, so hair Feeling shaky & nervous for no reason. Could this be hypertension or thyroid causing skin issues & swelling?
