Exactly sounds like your UTI have come back. Actually, UTI is a common recurring type of infection, after your treatment you should handle it very carefully to prevent a recurrent one. Try to begin each day with a glass of warm water with the juice of one small lemon squeezed into it. Lemon juice changes the PH of the blood and urinary tract so that the opportunistic bacteria are less able to proliferate. Urinary tract infections thrive on a damp and acidic environment. Lemons (unlike other citrus fruits) have an alkalising effect on the body. Cranberry juice helps as well. It's also important for you to limit your intake of foods which can aggravate urinary tract infections, particularly if you have an infection or feel one coming on. These include: alcohol, coffee, sugar, tomatoes, citrus fruits, soft drinks, vinegar and yeast. UTI sometimes may develop drug resistence and thus couldn't get treated by the same antibiotics. You may consider an alternative therapy such as herbal medicine diuretic and anti-inflammatory pill, it works slowly but can always help to get rid of diseases more completely, you may google it and have a look. Hope you'll be fine soon.
Yes, that could be UTI. Herbal medicine for UTI is good.
