Pain

I have been working out in a boot camp environment and walking every other night. On Friday I had taken the day off from working out and on Friday night I was in terrible pain. This was pain all around my port, now a week has almost past and the pain is less but I feel like my port is being hit by my rib cage. Anyone experience this? I feel fine, I can eat, breath, I have no nausea, heart burn or a fever. There are times that I am unable to swallow and there is no fluid in my band.
