It has been a while since my last post. It sounds that the diagnosis of a viral attack is pretty similar to my diagnosis supposedly stemming from the flu shot.
Since then i have been making strong steps. I am by no means back to normal, but i am at least getting the strength much closer to the other side. I am hoping by the 1 year anniversary of the initial pain I can be at least 90% back to normal. My pec muscle is still smaller but getting there. The lat is the same way. The tricep is taking a little longer, but coming along.
The only advice to people is to try and stay positive and keep working, it will come back.
