Chronic Cold and Throat Pain. Take any.

Till 6 months back, I used to always have cold and throat pain. Medication never helped. I had tried allopathy and homeopathy. Even If I was relieved from it, it was temporary and it always came back. I never used to drink or eat anything cold because of this. Present( 6 months straight without medication), I was fed up with medication and decided not to take any. Thanks to the last homeopathy treatment which worked the most. Most of the time I don't feel the symptoms of throat pain or cold. However it comes and goes naturally sometimes. And, even today I am scared to eat or drink what I wish to. Although I am taking all the care, I am not able to study properly especially in the times of exams because when I focus for longer durations, I feel sore throat instantly and it makes me very ill. I have been looking for answers since 3 years now. I wish to lead a successful life without my health pulling me back and eat what I want. Hope I will be healed with your help. Thank you!
