DD2 has had bad headaches since last week, they appear to be sinus (temple, below eye, worse when bend head forward). Took her to docs yesterday and he agreed and gave us some antibiotics but admitted they may or may not work. Soooooooooo when will they kick in if they ARE going to work? AND if they are not going to what can I do to help her? She is on max dose paracetamol and ibuprofen and is still in pain. Am getting very stressed and headachy myself now because I feel helpless.
