I started a cycle of Winny on Wednesday, and I started getting a pain on Friday, and it's been constant until now. It's about 2 inches below my belly button, and spreads out to either side for about 3 inches. It's not a pulled muscle, a hernia, a kidney stone, or a urinary tract infection, or anything like that, i don't think. It really hurts to run, or twist, and I play a sport so I have to. It hurts the most when it feels like my insides move. I was just wondering if this is normal, or if anyone had anything that could help out. Please!!!
