Sore throat, throat infection. Worried?

I am suffering from throat infection from one and half month. It started with chronic Acid Reflux, then after treatment the acid reflux is clear now, bit throat pain and congestion in throat is there. Also I feel a very small lump on the left side of neck. I addition, I feel very bad taste in tongue and mouth, more amount of white colored saliva( jhaag wala aur chipchipa thook). and my tongue gets white every morning, and get cleared after brushing. I consulted a senior ENT doctor. He  did endoscopy of throat, and said it is not Cancer, and gave me ten days prescription, including antibiotic antacid vitamin c, inflammation tablets. Now after ten days, I am still feeling something stuck in my throat while speaking. In morning(after waking up, my voice becomes stronger. Also, I feel pain in both side glands in throat. Also I feel my back as warm. Should I be worried? Please suggest.
