MHarley, There are a lot of possibilities to why the night pain, but this is something to track. At 4 months it is still difficult to assess whether you had any damage to the repair from a fall. How exactly did you fall and how has the pain changed or not changed over the past few months??

It is too bad about the therapy visit cut off. I would really try to get more visits and if impossible then pay out of pocket
for a few visits with a good manual therapist to evaluate your neck and shoulder and make sure there are not glaring issues that can be resolved with a therapist. You spoke early on about the neck, is it absolutley clear this is not causing any issues??? It took me nearly 4 months before I could sleep on the affected side without discomfort. I would try to get another MRI if this fails to improve the pain.
At month 5-6 your OS should be able to perform an MRI see into the joint and with contrast can tell whether the lession has healed.
