My back is paining me on the lower (mainly left side). It hurts the most when I move from side to side; does not hurt when I am sitting. It is below the waistline. I have a 30% kidney function; therefore, I cannot take the drugs to relieve the pain. Could it be a vertebrae compressing some nerves?
Welcome to Chat Doctor After going through your query I came to know that you are suffering from muscular pain. Treatment of it is rest. Due to kidney disease you can not take analgesic. You can apply topical diclofenac gel. Muscle relaxant can be taken. Vitamin B-complex and vitamin C supplementation can be used to promote healing.  It is unlikely to be vertebral compression fracture as it does not hurt when sitting.However, you can get lumbar spine x-ray done to exclude it. You can discuss with your treating Doctor about it. Hope I have answered your query. If you have any further questions then don't hesitate to writing to us. I will be happy to help you.
