"i used this stuff on my sprained ankle after my uncle told me that his doctor recommended it for pain and inflammation. i gave it a go and i found after about 10-15 minutes the pain i had been experiencing was virtually gone. i also found that it helped heal the bruising on my ankle as well. i have fibromyalgia as well and never thought to use it on my joints, i&#039;ll for sure give it a go! the only downside to this product is it smells really bad."
