How Can Inflammation And Pain In The Lower Back Muscles Be Treated?

my question is complicated:) my husband formerly experienced a fib which was treated with cardio version and ablation. He no longer has a fib symptoms. He does however have a lot of inflammation pain in primarily his back muscles -lower and rhomboid area. He is not currently on any meds except one aspirin per day. He is looking at possibly taking a product called Rezume which contains the following : White Willow Bark Extract, Andrographics Paniculata Extract (ParActin®), Tumeric Root, MSM, Yucca Root, ILEX Paraguarineses (Yerba Mate Leaf), Boswellia, Devil s Claw Root Extract, Ulva Lactuca, Naringin and Hyaluronic Acid. I was researching to find if any of the ingredients could be harmful.
