Dude...don't go feeling around in there yet, you'll likely fukk something up. I did not answer before because it seems like it's always the same question's from you.
If it's liquid in there, then it's perfectly normal and your body will soak it up within a couple of weeks. If too much liquid gets in there, then your doc will stick a syringe in there and extract it, but it sounds normal at this point. STOP POKING AROUND IN THERE. I'd hate to see you do any damage.
All you can do right now is wait it out. It sucks, but you have to go through it. It takes time to heal. Did you ask your doc about the vest yet?? Compression would help, believe me.
