I am a 20 year old female, non-smoker, non-drinking, college student, and am suffering from severe lower back pain that makes it hard to move. I have never had pain to this extent in my lower back, last day of my period was October 31st, 2011. I am also dealing with increased fatigue and urine that is very cloudy yet retains pale yellow/cream color, there is no change in odor of vaginal secretions. However, there has been uterine cramping, no history of cysts. I am sexually active in a long term committed relationship and we use birth control pills (Tri-sprintec) as the primary contraceptive and condoms as an irregular back up. Stress levels have not increased beyond normal, no weight loss, only weight gain of 23lbs, two home pregnancy tests and my period (I was on time) proved I am not pregnant. I suffer from Lyme disease, babesiosis, and arthritis. I am currently taking Singular, Quar, and Tri-sprintec. Any help would be appreciated.
