Yesterday, I Had A Hospital Appointment For My Long Lasting

Yesterday, I had a hospital appointment for my long lasting bladder/kidney problem because my urine wouldn’t come out and I’m having stinging pain when urinating. I forgot to tell the doctor that I wake up in the middle of the night because of pain. I’m having a ultrasound for my bladder and kidneys in 6 weeks. My left side is really painful, it’s achy and throbbing. It’s below my ribs. I had a kidney infection before at the beginning of August and I was on antibiotics so I’m not sure if it still could been a kidney infection or something else. In the meantime, any idea on what I could do for the pain? The pain is constant and is still there after taking painkillers
