"I am 4 months pregnant and I applied a cream with menthol, is it serious?"

It is generally recommended to avoid using products with menthol while pregnant due to the lack of concrete data on their safety. A one-time application should not cause any problems, but for pain relief, it is best to use acetaminophen and apply ice wrapped in a damp towel for 10 to 15 minutes as often as needed throughout the day. Consulting with a physiotherapist is also recommended for evaluating and treating this type of pain, as they are the best professionals for this type of issue. Additionally, most collective insurances cover this type of service.
