I had a level 3 separation: a clean 10mm separation. my prescription: P.T.
After about 6 months I could roll over on that side in my sleep without waking up. now about 16 months later, it’s still quite “separated” but pain free. My opposite shoulder’s had a few minor separations and still has a little collarbone protruding. I know a few other people that both had surgery and didn’t have surgery for separations. None of them are quite put back together right either. I’d say it’s normal, but what do I know… I’m a project manager… 
Good luck and heal quickly!
Since this thread is resurected, I’ll go with my little story…
I had a level 3 separation on my right shoulder when I still was a judoka.
Since one ligament had broken it wasn’t that painfull (it ached but mostly because of the ligaments that didn’t break and were slightly stretched).
For some reasons (paying the holidays, as I was still a student) I really had to work, picking parcels in a storage for 2 month (meaning I lifted more than a ton every day) and had my surgery after the holidays.
My collar bone was so worn out because of this that they ack-sawed its head and screwed a plastic thingy to replace the ligament.
I have no sequel at all, the surgeon said I’d lose some moving range but it didn’t happen, or so slightly that it’s unnoticeable.
I was told that it wasn’t necessary (and haven’t had any problems with rejection). My body likee the ligees methinks
A Judoka is what?
Sounds like a very secure result. Nice to hear your recovery. These injuries must be somewhat common for us uni-guys, eh?
Mine was from over-shooting a step-up on my downhill b*ke. My knee ligament injury on the otherhand… that was uni related. 
Cadaver ligaments, cool
I thought that my collar bone stuck out a bit more on my right (injured) side for quite a while but I now think that it was just that I lost a fair amount of the surrounding muscle during the healing process but it is all even now.
Basically my shoulder is great, I hurt it a bit two summers ago (two years after injury) when I messed up a 20m (65’) jump into water. I got it checked and turns out I broke up some left over scar tissue and once that healed my shoulder went from feeling basically normal to completely good and I have not had any problems at all with it since. For those first two years it would be stiff in the morning if I slept on it, now it doesn’t matter how I sleep.
My leg were they took out the muscle casing on the other hand still has messed up nerves in a slowly shrinking spot now only about two inches long in the centre of the area. If I have to carry something heavy that rubs against my leg I still try to avoid that spot.
An interesting discovery for me regarding scar tissue is how it can actually prevent proper healing. My chiropractor/sports therapist used the Graston Technique on my knee to break up scar tissue. Not pleasant… but after 8 or 9 sessions, the pain was gone and my knee felt stronger than ever! highly recommended… http://www.grastontechnique.com/FAQs.html
Judo “fighter”
Tried to reach my cadaver to find out if he has problems in the area of tissue removal, but I can’t seem to RAISE him. I’m willing to bet he was none too happy about his unfortunate loss of tissue either… heheh.
Seriously though, that’s a real bummer. I’d rather have an ongoing problem with a shoulder than a problem with my leg any day.
No way man, it is only surface nerves that were messed up, nothing structurally wrong but just a spot that senses things differently. I like having everything working properly, just a small spot that doesn’t feel much and gets an odd sensation when you put a lot of pressure on it is a small price to pay for a strong shoulder, especially when your livelihood depends on being physically fit (commercial fishing/firefighting)
At the rate the spot is shrinking it will be gone in another couple years.
