Hi,
Noted your history of donating plasma, I think it is
blood donation and you developed pain in abdomen, rumbling and
diarrhea.
I think this is heard for the first time in my life.
The most probable cause I can think about is the
anxiety or the stress that you developed.
This causes symptoms of IBS that is
irritable bowel syndrome.
So do not worry.
If the symptoms persist consult your Doctor for clinical evaluation and send sample of stool for tests as there might have been
gastroenteritis that developed at the same time. Get treated as per the cause found, if required.
If the problem settled then this might repeat with similar incidences which gives you stress and anxiety.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, General Surgeon
