Question:Which substance can cause a burning sensation in muscles that are worked intensely?

Lactic Acids.

I listen to the answer that was here before this one and I quickly found that it was wrong and it was indeed lactic acids. I hope this helps, if not you then other people who might stumble upon this question like how I did.
 
Thanks and have a nice day.
