I have had sinusitis 9 months after a fall when I struck my head on concrete. I had two courses om Amoxocilin which helped but did not resolve. I tried sinus rinses which also helped but did not resolve it. By chance I started to use a vibration plate exercise machine and it has really helped. The reason may be stimulation of the lymphatic system which drains infection. I just wanted to share this information and to hear from anyone who has found the same effect. I tried to tell a vascular surgeon, who deal with lymphatic systems but he blanked me.
which vibration plates did you buy and also whereabouts on your neck - as I feel this started on my neck when driving - I may try and manually do this on my neck to see if it helps
I bought it on eBay for £50 but as far as I can see it is an i-fit and is a commercial quality machine. I stand on it for 20 mins a day, in four 5 minute episodes with knees bent and it has really made a difference.
