My weight is 82 & i have slip disc problem please help me out sir?

Weight of 82: I assume that's 82 pounds and not kilograms, indicating that you're underweight. Of course, without further history to explain the low weight, it is hard to provide specific advice. If your macro and micro nutrient intake is deficient, it may be affecting your bone health, which might result in your back problems. You have probably heard it before, but you need to consult a doctor.
