Does drinking cranberry juice really cure a UTI? If so how much do I half to drink of it? How can I get rid of a possible UTI without going to the Dr?

Cranberry juice... ...wont help. For several years it was believed cranberry juice could prevent or cure UTIs, but recent research shows no significant benefit. You may not have UTI anyway. UTI is rare in males your age (22). STDs are more likely cause of painful or urgent urination in young males, especially if you've also had urethral discharge. Don't cut corners; you need to see a doctor for sure. Good luck!
