Thank you for your question. It is possible that you may be suffering from either allergic rhinitis or a sinus infection. The treatment regime for each of these is different and we therefore cannot offer you an over the counter remedy without further examination. We recommend that you go for an examination of these symptoms in person by a doctor in order to be prescribed the appropriate medication taking into account that you have a preexisting medical condition of diabetes.
