Sinus Medication Solution

I’ve been suffering from ear/sinus pressure a little over a week now. I’ve been to my doctor and he said that I don’t have an infection, just pressure. I’ve been taking Sudafed, with no luck. I’m now trying Mucinex D and Claritin D. No relief so far. Has anyone else ever had this happen? How long can I expect the pressure to last? It’s driving me crazy!!!
