My throat has been hurting for 6 months continuously, what should I do?

My throat has been hurting for half a year now and it is on and off. On and off in the sense most of the times it hurts really bad and and rarely I can barely feel it. It hurts to scream and sometimes my voice turns hoarse for some reason with me not doing anything and I have to clear it out to get my voice normal. And sometimes my right or left year get sharp pains for a few seconds and then it goes away. I have been telling myself to got the E.N.T , but I never have the time to go. I am busy constantly...I have been getting sick more often than I usually do and I feel that it isn't normal. I have been to the regular doctor, and they either say it is mono or allergies. But I know I have no allergies because I have recently got a test done. The next time I go to the doctors I will go to the E.N.T. But do you guys have any opinions what it might be causing this throat pain before I actually go to the doctor?
