My post disappeared, unless there is more than 1 thread on this topic. I want to share that 2 months of Physical Therapy really eased the frozen shoulder pain that developed from the flu shot, which I received a year ago, August 2010.
For months I couldn't sleep on that shoulder, I couldn't raise my arm beyond a certain point, and then I couldn't hook my bra in back. It was going on 7 months before I finally went to see my Dr, who assessed that I developed Shoulder Impingement Syndrome. No CT or MRI needed (only an Xray to rule out calcification). And Physical Therapy.
I couldn't afford to go 3x week, so my PT guy gave me the exercises to do DAILY at home (which I did every single day), and I met with him once a week for 2 months.
My shoulder continues to improve. I can sleep again on that side without interruption, I can raise my arm, I can hook my bra.
I won't get the flu shot again, but there is hope through Physical Therapy (I was injuring myself by trying to do it myself, looking up exercises online, without guidance).
