<s>[INST] I have lower back and side pain,a dull headache, and today some diarerria. I have had the pain in my back since Sunday. I have been sleeping a lot also. I don t like feeling bad. I am visiting my daughter in WI, and if I don,t start feeling by tomorrow I will have to go to urgent. What is your bes educated guess? [/INST] Hi Welcome to HCM.I understand your query and concern.You seem to non specific low backache and headache coupled with mild infection of the gut.This can be treated with analgesics like ibuprofen and antibiotics like metronidazole.Antidiarrhoeal like loperamide will also be helpful.Please note all these drugs have to be taken under strict medical prescription only.Drink plenty of fluids like water and fruit juices amounting to 3-4 liters/day to avoid dehydration.This therapy is all that is enough in your case.Consult your Gastroenterologist for expert management.Post your further queries,if any.Thank you. </s>
