port incision/nausea

I was banded almost 3 weeks ago. Currently have a large lump under my port incision along with pain, tenderness and difficulty bending, getting up and down, etc. Other incisions feel 100%. Was told by the Dr. it is a pocket of Fluid built up that will go away in 3 to 7 weeks.

Also having constant nausea. I have no desire to eat and have been forcing myself to have Protein Shakes and other full liquids. I feel so sick at my stomach and horrible....have been trying to drink lots of Water to prevent dehydration.

Am just wondering is this is common and how long it lasts. Anyone else experience either of these following their surgery...Any feedback would be appreciated. Thanks.
