"Out for 2 hours"

I hadn't even been out of the house for 2 hours , when I could describe feeling the following.

Excruciating nerve, joint, bone, muscle, back and feet pain.    I know that pain management is not going to want to raise my meds but what the hell am I supposed to do?  Now that I'm sitting at least some of the foot pain is relieved but this really is ridiculous.  It's not like I ran a marathon, I'm just out doing my errands on foot!
