Whats happening with my band??

I have been banded for one year and 6 months now and for a month i have been feeling this "Click or Nudge" type of pain where my port is located (Between breasts)

I went to the doc, and he said nothing was wrong and gave me pills to reduce infection IF I HAVE ANY as he said.

No tests were done.

I have been waking up daily in the night as if i was choking BUT my band is not tight at all! Im @ my sweet spot.

Yesterday i was having dinner, i guess i did no chew well (brocolli) and i vomited, which caused my stomach to Twirl or how can i put it, i felt as if my stomach was being squeezed as if you squeeze Water out of a towel, i have PB'd many times but this was the worse!

Today i feel like u know, clicks or flickering on my port, (sorry my english is not that good)

I know u will say to go and see the doc, but im on self pay and he is REALLY expensive and if i were to see him i should wait for next month till i get my salary.

Please is this something A BIT normal?? am i feeling port malfunction??!!!

Thanks
