Hi Thanks for posting on HCM The symptoms you describe sound like gastroenteritis.Electrolyte imbalances that accompany diarrhea may give you symptoms like tremors.Possible causes of your condition could be bacterial, viral, parasitic infections.Other causes may include food poisoning, lactose intolerance, drugs induced digestive disorders.I will suggest you see the Doctor for examination and investigations.You may need test like full blood count, stool exam/culture, serum electrolytes, H pylori test if signs of acid reflux.Your treatment will entail treating the underlying cause of your symptoms and correcting fluid and electrolyte imbalances.You may try the following: -Take oral rehydration salt -Zinc tablets -An anti-diarrheal like imodium -Fruits like bananas that may help harden your stool -An anti-secretory like omeprazole -Pain medication like paracetamol for headache Your Doctor will take care of the rest after the results of the tests. Hope this will help Wish you a speedy recovery
