Muscle Rub a danger??

Hi, I bought some Bell's muscle rub to relieve aching muscles and rubbed it on my legs before going to sleep. My partner was woken in the night by me having a hypo and she managed to feed me glucose until I recovered.
Has anyone else had, or know of, adverse effects relating to muscle rubs??
