I have had a burning sensation when i urinate, and pain when i have a bowel movement for two days, today i have a severe pain in my upper left leg/buttocks. It is so severe, it woke me up last night and now i can t seem to sit down, it hurts so bad. I am athletic and not overweight, BMI = 20, i just turned 56 years old (female). I have never had a urinary tract infection, but my 18 year old has and she had blood in her urine - i don t. help!! i have to ride in the 33 mile bike ride with my team on Saturday, and i am worried. Should i see a doctor? thank you
