I recently had a tooth extraction and was prescribed penicillin and motrin 800 mg. This was 10 days ago. I have only taken four of the motrin, as I dont really feel how they help with any pain. Instead I finished off a bottle of Tylenol 3 that had been previously prescribed by my dentist for different extraction. Not sure why I was prescribed two different pain killers, but it is a father/son denistry and both did extractions on me. The most recent one was difficult and after two follow up visits, it is healing fine, but I was told to finish off the penicillin, which I did today. So I have taken penicillin for 10 days, stopping today. I have also occassionally taken an Advil PM to sleep when the pain killers didnt work during the worst of my tooth pain. Yesterday, after not having eaten this in months, I made a bad choice and had a McDonalds cheeseburger. It usually upsets my stomach and that is certainly what happened, as I was up at early hours of the morning in the toilet. Finally it turned diarrheal, which is always a sign for me that the worst of my digestive issue is over for that episode. However, it has lingered throughout the day. Finally, I had another bowel movement around noon or so and it had no smell, seemed to have some blood in it and it was dark and sort of shredded in texture. My stomach pain is still lingering. I learned antibiotics can wipe out good bacteria that helps with digestion and so Ive been eating yogurt with a lot of cultures since that fearful bowel movement. I know I need to see my doctor, but from the sound of it, does this sound terribly serious?  I also have to take iron for anemia, but Im very slack on that every week. I take a womens multivitamin daily and for the past few days Ive drank a smooth of kale, strawberries, cucumbers, yogurt, and almond milk which has helped my bowel movements. I have a history of constipation but it has gotten a bit better with me incorporating better foods and cutting down on fast food. I dont exercise at all, which I know is a huge factor. I have also tried maca root twice this week, just a single capsule on two separate days and felt no effects. I did this after researching a natural way to gain some energy. I work from home, so again, not very active these past few years, but I plan to definitely change that. I dont drink quite enough water according to my doctor, but do not drink much of any other liquids either, mostly just bottled water and ginger ale. I have a history with what I believed to be gluten-intolerence where eating things Id always eaten, like oatmeal and Nutri-grain bars, would break my skin out, actually peeling away a top layer of skin in circle-shaped break-outs. I have not seen one of those on my skin in years, but still stay away from certain what products while Ive began to eat others that I had shied away from, like granola cereal.  Overall, eating red meat isnt that common for me. I eat little meat generally, mostly chicken, fish, and the occasional bacon. That is pretty much all of my health history and lifestyle.
Hello, Welcome Thanks for consulting Chat Doctor, as u mentioned that you have undergone extraction, and you have taken good amount of antibiotics as you have constipation problem also I will suggest that you don't worry about that take a course of vitamin B complex for one week twice daily it will help you and if problem continues then consult physician.
