Yes he has a cyst and it went through the other side. You need to lance the bad side and get it out. Hopefully you won't need to do the other side. You will have to cut the bird like I did. Start at the bottom of the lump not the top near the eye. Be sure you have plenty papertowel he will bleed a bit. I cut the bird and held a papertowel til it almost stopped then cut some more. A little at a time for the first time. If you lived by me I would say bring the bird over and I will show you. I still cringe when doing it though. Here is another thread showing the cutting involved:

If you know a vet you can always show them the threads and see if they will do it if you are unable to. If you do not remove the cyst the bird will die on you, good luck and keep us posted.
