One of my goldfish looks bloated and has lumps on it's sides.  They are not open or red.  It is still swimming and eating a little.  I am not sure what to do.

We have had these goldfish since last Thanksgiving.  They had Ick shortly after I got them.  I treated them and they have seemed fine since.  The other 3 fish in the tank look ok so I have taken the one fish out. 

I have searched the internet but I haven't found out what is wrong with this fish.  Can you help me?

Thanks

I have sucessfully saved an overfed fish by not feeding for 2 days, then feeding a skinned, thawed frozen pea to get things moving (less than a whole one per feeding for a tiny fantail) on day 4 start feeding sparingly with frozen brine shrimp from your pet store if you can get any. I wish you well, Hang in there, little fish!

Also, make sure your water quality is perfect- he's already vulnerable now.
