I Have Had A Cold Virus On And Off For

I have had a cold virus on and off for a month, with what seemed to develop in to a sinus infection on the left side. Painful upper teeth and pain across left cheek bone. I have now developed a pea sized lump on the left side of the bridge of my nose between the bridge and my left eye. It is extremely painful and I now have a constant headache and some pain to the eye. I feel pressure now to the inside corner of my eye ball and upper and lower lids. The lump is painful, hard but movable. There is no head, but the area is a little red. Does this sound like a cyst or could it be related to the sinus issue?
