I’ve been having severe upper stomach pain for about 3-4 days. My stool was black and had a clay-like texture the 1st day. The past couple of days it’s been really loose. I am still having stomach pain and my stool is still black. Wondering if this important is enough to go to the hospital during this COVID-19 epidemic. I’ve been in bed for the past week and only get up to use the restroom. I don’t know what I should do.

The only change in my stool is the shape, more of a pile. No other symptoms except very stressed. I only go once a day. I had E. coli and MRSA about a month ago, diagnosed by lab. I am being treated for MRSA presently.

I took 4 ferrous fumarate tablets in a period of 2 days and I noticed that my stool was black the following days. I was surprised by it but ignored it until it changed back to its usual color. I didn't know what had caused my stool to become black so I did research on these ferrous fumarate tablets that came with the levonorgestrel and ethinylestradiol tablets.

Well, my bowel movements have turned too liquid, almost like water and copper colored. My lower bowel is partially collapsed. This is a new symptom, and it happens as soon as I eat; I am not metabolizing any food. I have weight loss and very smelly bowel movement, even the liquid.

What an experience. I had been feeling slightly weak for a couple of months. I had been taking Ibuprofen for a year at bedtime just to sleep better. Huge mistake. I took one or two. My grown daughter kept me very upset all this time. One night I had black stool, bleeding all night long, and grew quickly too weak; I could not walk or stand. I was sweating and by 6 am called for my husband who could not hear me. So I called an ambulance myself. I was in a trauma unit for five or six hours and had half a dozen lines in my arm. I had my most painful experience ever in an in and out catheter. Do not ever agree to it. I was screaming. I never got up for 3 days. I had an upper endoscopy which was totally painless and almost enjoyable. They found multiple bleeding ulcers in my stomach. On day two they had not fed me anything. They woke me up every hour each night to stick me with needles and take my blood pressure. The rubber sheets kept my bed wet. Then the liquid diet began. My blood reading was 8; they spoke of a blood transfusion and gave me a heart monitor. Two hours later the doctor said I could go home. I thought I was dreaming. It has been 3 weeks since the bleed in my bed and I am walking around some, my stool has just began turning brown again but I stay in bed half the day. My doctor said I had been in very serious condition. I am on the usual medicines plus I bought a probiotic and krill oil.

It's pathetic that today's doctors are often shy about stools. I've had abnormal stools for a long time because I didn't know they were abnormal and no one asked. I also thought it was normal to have extreme discomfort from defecating. Doctors suggest OTC and other things I've tried for over a decade! There are signs of blood and other irregularities. They just don't care. I asked to see a specialist and the primary might as well have given me the bird.

I've been having small white fecal droplets with blood.

For the past few days, I have had bright red blood in my toilet after a bowel movement, one day last week, and it still won"t stop bleeding! I had a painful bowel movement that day and I felt a scratch 2 times. Like I said I have had the bright red blood, not to mention, when I stand up, blood drips on the floor. My husband wants me to tell my doctor or go to the hospital and I really don"t want to!

Back on New Year’s 2011 I was the victim of a hit and run. A 2000 Pontiac Minivan struck me while I was crossing the street, at 70 mph. A lot was caused from this including me living with a plate and a shunt, but this post is for this large lump on my outer thigh from where I was hit. I’m almost sure it is a hematoma even though I remember them saying “muscle bunching” back then even though it’s clearly not. This lump has been here for 8 years! I wonder if anyone else has had a lump for that long.

A week back, I had diarrhea. It was normal; brown, liquid and frequent. Two to three days back, they were still frequent but the quantity had dramatically reduced. The first day, I had this black kind of mucus. It only happened once. After that if I had normal brown feces, then sometimes they'd have some tracing on them and sometimes they would be normal. Same goes with mucus; which has thankfully not been black again. It's dark red or brown. I wonder if eating a lot of ketchup can be a cause.

I have been taking venlafaxine 37.5 mg capsules once a day and it has changed the color of my stool to yellow.

I have been on multiple antibiotics over the last month and have had MRSA. My stool has been yellow to dark green. I have had diarrhea for over two weeks. I am now on the BRAT diet and it has slowed it down but has not stopped the diarrhea.

I have been having black stool for the past two months now. I don’t know what could cause it. I am worried.

My poop color went from normal to pale yellow this weekend. I had been drinking a lot and not eating as much as I should. I have had some pancreatic problem in the past.

Noticed for the last 10 days my stool has changed brown color to mustard yellow color. It is also softer than usual. No other symptoms. Health is good. Diet has not changed.
