Muscle pain creams and pregnancy

Hala2010

I had an awful leg ache from walking around all day, and as I usually did pre-pregnancy, used a muscle rub on the affected areas. Then DH realised I was pregnant (20 weeks), looked up the active ingredient (methyl salicylate), and started freaking out. Something about an ounce being equal to a whole lot of aspirin, and was toxic for the baby/ could lead to malformations etc. I ended up washing it off 10 minutes after it was put on. Has anyone had any experience with this, and how did it turn out? I believe many muscle pain relievers (eg. Bengay) have the same active ingredient.
