Face numbness symptoms and conditions

I was recently diagnosed with Hoshimotos Thyroiditis. It's only been three days since I have been on the Levoxyl (100 mcg), but I am feeling slight chest pain and tingling in my face. My heart isn't racing though; it's just a dull pain! I am nervous that it will continue to increase and that other symptoms will come about. Just reading about people's experienced on this site has made me nervous too! Has anyone ever experienced this and if so, did other symptoms follow?

Thanks for your feedback!!!
