Chronic pain and tingling sensation in both legs, please advise?

I am a 23 year old female with chronic pain and tingling sensation in both legs accompanied by issues with urinating. I have had to urinate multiple times in just a short 30 minutes…some times i feel like i can’t empty my bladder. My legs have been hurting for about 6 months. They hurt all day every day and even wake me up during the night. I can’t find relief with anything…please help.

Age: 23
Female
Medications: Synthroid, zoloft
General Information: Saw a doctor and had xrays done. Went to an ER one time because the pain was radiating to my abdomin and back..urgent care said there was blood in my urine and figured I was having a kidney stone. They gave me a shot of muscle relaxer which did not help and sent me to the ER for a CT and they refused to do one.
