If someone had kidney or liver failure, would they have a normal liver and kidney function blood test? My stomach is bloated badly, I’m getting stomach cramps and some breathlessness, which I know can be caused by pressure on the diaphragm. I’ve had 4 lots of antibiotics in 2 months, a bladder infection in Feb, which has now gone and a clear x Ray. I had a troponin test in March which was clear - as had a massive heart attack three years ago. My legs, though not swollen, feel some discomfort and there is loose Puffy skin at the top of my feet which I think looks like mild Edema. My partner disagrees and is at her wits end as I have been feeling rough now for 12 weeks. I have had two negative Covid tests but my GP said the tests need to be within a short window of symptoms starting, so she would expect them to be negative and that there are a lot of false negatives. My other concern is heart failure. I had a massive heart attack three years ago and done really well and recovered fantastically. I am walking 3-5 mikes a day in total so would think this would not be possible if it was the heart causing problems.
