Sayang, ini macam sakit yang serious dan kena consult doctor tu, especially kalau pregnant, jangan delay okay. Condition ni memang rare dan kena expert advice, so please see your OB or go to hospital kalau sakit tu severe or sudden. I haven't come across this in my circle of mum friends either, so honestly ini bukan something most of us encounter. But sakit kat muka/nerve area tu memang kena proper medical check, your doctor kena tahu especially if you're expecting, sebab ada certain things that are safe and some yang tak during pregnancy. Don't wait on this one, hun, better safe than sorry!
