Hello! I'm A Little Concered. So, I Went To The

hello! I'm a little concered. So, I went to the ER last night because I was very dehydrated. I was very dizzy, couldn't walk, had a terrible headache, and I even lost feeling in my foot. They hooked me up to an IV and my dizzyness felt like it was gone and I gained more energy. But my head ache was still there. So, the doctors gave me 1000mg of Tylenol. They gave it to me around 12:15am. And about 5:30pm today, I was going to the bathroom and after I wiped, I noticed light red blood in my stool. Should I call a doctor immediately or wait it out? Please Help!!
