After 7 days I revisit he suggest me axavic cv tdpc for 5 days and rabeprazol, montair lc. After 10 days He did endoscopy in my throat and told everything is okay and suggest me to gargle with raw betadine.But 4 days ago infection recured then Dr. gave me LNZ 600bd for 7 days,xylomoist nasal drops,pan d and montair lc .I take LNZ 600 3 days but infection not cured. I am very worried.Please suggest me what should I do? My CRP-1.6 CBC in normal range HIV negative Should I gave throat swab for culture? I was smoking but last 45 days I not smoke.
