I think losing weight will absolutely help your back. I knew someone who had back problems (lots of pain), and she lost a ton of weight and got down to the lower-normal end of her BMI range and worked out, and she said her back pain all but disappeared. Her doctor was thrilled and advised her to maintain the weight loss to keep control of the pain. Worked great for her!
This is a good place to get support. There is a lot of information in the archives. Also, there are challenges (for exercise, weight loss, etc.) that you can join, also different threads based on things about you or your interests that you can join if you want.
What's your plan for losing weight?
