Lump in my throat

I have a small problem and was hoping that some of you could maybe shed some light on what my problem is. I first noticed my problem around 3 months ago. When I turned my head to the side and swallowed I noticed that I felt some kind of itchy feeling in my throat. I didn't have any pain, just an itchy feeling. Soon after my gf's throat swelled up and she went to the Dr. He prescribed her antibiotics and in a few days she was fine. I kept on having that weird feeling in my throat though. So three months go by and the feeling is still the same. Recently though I have noticed a small pea sized lump on the right side of my throat just below my adam's apple. I have also been really tired and show some signs of the flu. My throat is not sore, but I feel the lump every time I turn my head to the side and swallow. That is the best that i can explain my condition. When I turn my head to the right and swallow I notice a dry feeling in my thoat. Any help would be greatly appreciated. thanks.
