Hi, Thanks for writing your query. It would be helpful if you could undergo comolete hemogram,electrolytes and stool examined (Routine/Microscopic,ova,cyst and for Occult blood). Swallowing difficulty could be as result of throat infection which can be cured easily by antibiotics course. You can take Metronidiazole 400 mg thrice a day, antihistamines (tab.avil or cetirizine available over the counter) along with an antacid like Ranitidine 150 mg twice day and a probiotic preparation. Antibiotic like Ciprofloxacin 500 mg twice a day, if needed can be added according to the report of the stool examination. Take care of your diet. You should eat light food, prepared in hygienic conditions. Drink pure water only. If the problem persists, get yourself examined clinically by gastro-physician. I hope this is helpful to you.
