I've Constantly Been Throwing Up Ever Since Drinking Super Prep

I've constantly been throwing up ever since drinking super prep for my colonoscopy. That was over a month ago. Colonoscopy was normal. ER visit said nothing was wrong except my creatinine was a little to the left. The lymph nodes in my neck showed up 2 cm big. I also have severe pain in my thigh bone (deep, achy pain). My wbc has been at 11 for over a year and I have enlarged spleen and liver (nafld).
