Pain meds don't help my lower back pain, what can I do? I've been to the doctor's office twice and the ER once this week and all this, they can't yet tell me what's wrong.
I've been having abdomenal pain(which seems to have gotten better) and lower back pain(which has gotten worst!) The sharp pain in my back comes and goes, and when I lie down, it HURTS. I also have a constant dull pain in my back. Sometimes the pain goes down my legs and the whole area feels numb.
The ER peopole said I have an infection, but my regular doctor said my urine sample from 2 hours before I went to the ER is normal. I am taking antibiotics also. 
The second visit to the doctor tells me I may have a kidney stone. So I am waiting for an ultrasound and xray, which they did NOT do at the ER.
HOWEVER, this waiting period is 2 weeks and the pain med is not working. The doctor gave me stronger prescribed pain meds, but the pain is still there.
What can I do, in the mean time? Please help!
