Had a severe kidney infection about a year ago, and since then I have had constant pain in my back, in the kidney area. pain increases greatly if I drink anything other than water. Half a beer or a soda will cause me to be in tears a couple hours later. There is often a tearing/burning feeling inside and i feel like there is constant pressure. Pressure is somewhat relieved when i urinate, which is happening more often, especially at night. Also am dealing with loss of sensation in my hands and feet sometimes. (don't know if that is related) Am getting NO help from my doctor, who continues to tell me it's muscle strain, and don't know where to turn. The pain is unbearable at times. Please help!!!
