Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that you have got a seafood
poisoning due to eating crab that seems to be due to contamination of crab with bacteria, virus, parasites, toxins etc..
It has led to excess formation of intestinal gas along with disturbed intestinal function leading to diarrhea..
Crab pieces struck in throat does not seems to be a cause..
I would suggest you to
consult a Gastroenterologist and get evaluated and a thorough clinical evaluation and investigations like Blood tests, stool culture can help in diagnosis of the exact cause and treatment can be done accordingly.
You can be advised antibiotics if there is bacterial infection while anti parasitic drugs like
Albendazole can be advised for
parasitic infection..
As of now continue taking
Loperamide [Imodium] and also oral rehdration solution..
You should ear more of yoghurt, rice, bananas, cereals and take sufficient rest..
Hope this information helps..
Thanks and regards.
