Hi Thank you for asking HCM. I have gone through your query. Your problem can be most likely due to urinary tract infection. It usually gives fever with chills and associated back ache. You can go for urine routine examination to confirm this. Antibiotic therapy will be needed for this. I usually start antibiotics like norfloxacin and send urine for culture and sensitivity. Antibiotics can be changed if necessary after getting the culture report. Taking barley water or cranberry juice is helpful. Potassium citrate in water can be taken if pain while urination persist. Hope this may help you. Let me know if anything not clear. Thanks.
