I just starting taking Diclofenac Sodium Topical Gel 1% and soon as starting using it on my spine and hip my pain was reduced to a level 2. The first night I used it I had the best sleep I've had in two years and I didn't even realize I didn't have any pain that would suddenly wake me up in the night and I have to jump out of bed. It's worth trying as it's working for me and maybe we can help you all with your night pain or just pain. If you read about this drug you'll find that they only suggested using it for knee, ankle and hands, but there have been some treatment for back. It is for joints and your back has many.
