I Have Had A Four Week History Of Sinusitis, And

I have had a four week history of sinusitis, and received 10 days of amoxicillin for it without relief. I am hearing my heartbeat in my ears all the time, and am continually fatigued. Last weekend, I had nausea, vomiting, and diarrhea as well (about four days after I finished antibiotics). I am tired of feeling sick.
