For the last few days, I've had frequent urges to urinate and even after urinating, my bladder feels full. Toward the end of urination, I start to have a tingling feeling and it becomes harder to urinate but it's not painful. I'm guessing I have a UTI or bladder infection, but I'm not sure what kind of Dr. to see. I have an GYN, but not a primary care physician. What's recommended?
