Diagnosed July 2012, given LP which relieved much pressure and excessive fluid. On prescription acetazolamide to help with headaches and back pain. She's suffered all week with sinus pressure. Her family physician gave her antibiotics in case a virus was coming on. She tested negative for both the strep and flu. I just want my daughter to have relief from her sinus pressure. Is it safe or are their any other meds I can give her to help with symptoms?
