Urinary Tract Infection
"I was taking 2 tablets twice a day. I stopped because I realised this prolonged, dull heavy headache was caused by this. It was lasting days, I don&#039;t really get headaches and thought it was something separate. It&#039;s now Tuesday and I stopped them on Thursday after a week and a half. Still got the headache (which is really bad and no signs of going) , heavy head, light headedness and bad stomach. I&#039;ve noticed dehydration symptoms too. Stay away from this it&#039;s really bad."
