Hi, I ve had the flu (lasted about 2 and a half weeks) - and since Wednesday, I ve had super sore gums. Could this be related to the flu? At first I thought it was my sinuses, sore after constantly blowing my nose; but now I know it s definitely my gums. They are quite red and extremely sore.... gargling salt water, taking paracetamol and aspirin or even using mouth ulcer/ teething gels don t help - what can I do?
