The US Food and Drug Administration has warned the public that using over the counter muscle and joint pain relievers could lead to chemical burns.

Releasing a statement to the public, the FDA said, “These products should not cause pain or skin damage. However, there have been rare cases of serious burns following their use”. The health agency added that products in which menthol and methyl salicylate concentrations were greater than 3 percent and methyl salicylate concentrations greater than 10 percent could lead to severe burns that can require hospitalizations.
