I had sinus infection except I had no symptoms except sensitive teeth and felt a little dizzy with shortness of breath at times. I read it could be sinus infection I went straight to ENT and INSISTED on nasal smear it was positive for Ecoli the ENT dr prescribed some Antibiotics by day three I had hives .MY primary doctor gave me ointment that had me coughing and gagging typical response for me to any chemical in medications so this is what I did so I started taking a natural Antibiotic garlic berberine, and gse in orange juice in the mornings and afternoon . Vitamin C 6000,g to 10000 mg for 2-3 months is good idea I also had a ear infection so started 1/4 of one garlic clove sliced and wrapped in cotton ball put in my ears and wore a fleece hat and covered my ears with it so the cloves would not fall out . I would also put them in my nose prepared the same way but smaller if that bother you then just use garlic mullein oil. I would then put three to four cloves garlic in the good old magic bullet and get it chopped up and put in a bowl on my nightstand next to where I sleep and breath it in since you cannot have the cotton in your nose at night. Garlic kills anything within 20 cm so that is 7 inches. I read that garlic was put in petree dish with some super strong bad bacteria and it died within two hours so I suggest two hours . Since I stay home I even have a bowl of it on my desk until I feel that this bug is completely gone then I will continue to do this. The key is keep at for a long period of time to make sure it is dead that is why I suggest the natural route the aftermath and side effects are not as devastating.
