Hi Mike,
You have provided us with so much helpful and excellent information on this topic !! I have enough references now to help me mull through the difference between the SMP and SIP.. I think your summary of the SMP being there in the acute intermediate stage and evolving into SIP as the chronic stage develops says it all in a nutshell!!
I hope you had a happy Father's day with your family, and that you are seeing some tolerable and maybe even some enjoyable days!
Bask in the sunshine!
