Circumcision

[2unsure]

I was circumcised two weeks ago. The initial pain has gotten better, but now I have another pain. A quarter size lump on the left side of my penile shaft. When I touch it, the lump moves around and doesn't seem to be getting any smaller. It is painful and sometimes I wake up at night because of this discomfort. I am concerned. I feel as though I am disfigured and am worried that this could be serious. I am trying to get a early appointment with the Dr. who did the procedure, but am waiting for a call back. If anyone knows what this could possibly be,I would love to hear from you.
Thanks,
