Well, in fact he examined the lungs and didn't find anything suspicious but anyway, preventatively, he prescribed antibiotics. I wasn't wise enough to protect myself on my own at that time.
After completing the treatment with antibiotics I contracted Clostridium difficile infection in a quite severe form. I was very reluctant to take another
antibiotic to kill the infection and that was the mistake. Eventually I took the prescribed metronidazole. Lucky for me it worked and fought the infection (the proof that antibiotics are not always so bad). Unfortunately I waited too long and as a result I got IBS-D (diarrhea form of irritable bowel syndrome). I guess, at that time my microbiota (microorganisms living in the guts) was completely messed up.
As a result of frequent discharging (about ten times a day) I developed internal hemorrhoids (bleeding during discharge, no pain). I tried the methods described on this site but without success.
I was depressed. Finally, without much hope, I switched, in my daily beverages (tea, coffee, water), from tap water to spring water bought at a local shop.
To my surprise, it worked. After three weeks bleeding disappeared, discharging stabilized at once a day on average (although still every couple of days in a liquid form).
I should also mention that this changing from tap to spring water helped my mother-in-law to stop stomach mucosa bleeding caused by tonnes of medicines she is taking. Before that she regularly, once a year, visited hospital to have blood transfusions.
As I am a man of reason, I tried to find some explanation for this. The only explanation which comes to my mind is the following one.
Tap water in my city (as I guess is the case in most places) is chlorinated ie. chlorine compounds are added to water during its treatment to disinfect it.
Chlorine acts on the body as a drying agent (you can notice the effect of dry skin when washing hands in chlorinated water and this is not only soap causing it) and probably, as a result intestinal mucosa becomes dried up, less flexible and more prone to mechanical microdamage during discharge.
As for my IBS-D, it is still there, but in a much milder form. I guess the reason is imbalanced microbiota in my intestines. Most probably I should change my diet to cure it. I know that first of all I should eliminate sugar, but I am simply addicted to it.
I hope this simple and inexpensive method will help the people with similar health problems.
