I started on Keflex 2-10-15 for what appeared to be 2 insect bites on the back of my leg and the big lump was on my achilles tendon. 45 minutes after I took the first dose, I had severe diarrhea that was like I was peeing but it was coming from my bottom. I hadn't had a bowel movement after that. I ended up going to the ER because my stomach was cramping off and on and I kept getting nauseous. I was on it for 5 days. They said it was probably a side effect from the medicine and that the bite looked healed so they took me off it. The stomach pain continued off and on and I had not had a bowel movement for a little over a week. I used a fleet enema and only got 4 tiny pieces of stool out. I did notice one was floating and was half white. I went to my doctor, she found bilirubin in my urine ,drew blood and said my liver enzymes were elevated. She had me start taking Miralax for the constipation. The next day I had an complete abdominal ultrasound and they called me and said everything looked normal except that I had a lot of gas. A couple days later I got very nauseous on a car ride and when we got to the house I was very shaky, pale, and felt like I was about to pass out. Then I threw up one time. The Miralax wasn't doing anything for me after 5 days of taking it once a day so I called my doctor and she had me after taking the Miralax, take 2 capsules of Dulcelax. About 3 hours after I took the dulcolax I had 2 marble sized balls come out but that was all. The next morning I called again and they had me do another fleet enema and this time first just a few pieces came out, then it was very soft stool, a medium amount. I still felt like I had more to push out but I couldn't. I was also still very nauseous. Doctor said that's normal. Today I went for a check up on how I'm doing with the blood pressure medicine. I also told her that I get a burning feeling in my stomach a little above my bellybutton in between meals and that when I eat bread or thick foods, I have trouble swallowing them down. Yesterday the bite of muffin when I swallowed came back up. She said that was probably because of constipation? She said she thinks that the constipation is from my blood pressure medicine, Procardia XL 30mg. I tried telling her that I've never really been normal that I do tend to only have 2 bowel movements a week on average even before I was on any blood pressure medicine. She still thinks it's from the medicine. So she prescribed me to take Miralax and Lactulose every day. I still have to pick up the lactulose tomorrow but tonight I noticed I went 3 times, each time small bowel movements, and I noticed they are shaped like worms. Just the shape I didn't actually see any worms. The stools are about the size of my pinky each. I also noticed that some stool still has some white patches on it. I took a picture of the last bowel movement I had. I also noticed something sticking out of one of the pieces so I took it out and washed it off then scrubbed my hands clean then took a picture. I also have almost felt a tickling sensation on my bottom hole one of the first days I hadn't had a bowel movement yet and when I wiped there was a little clear/white mucus. I did have an increase in Prozac from 40mg to 80mg 2 days before I started the Keflex. Do you think I might have worms or something?
