Some kind of injury

Okay, not sure what happened, but a muscle on my back, along my left shoulderblade, is hurting a lot. (It was my right yesterday, and then shifted to my left after I started babying my right).

It was probably something innocuous like I slept at a wrong angle, or something. It doesn't feel critical? permanent? But it's been hurting hard enough/for long enough that I am putting lots of thought into not aggravating it further.

( some details )

Is there any way to tell whether the massage is a good idea, or whether it could be hurting me longer term somehow? And is there any way to tell whether I'd be better off trying to move those muscles slowly and carefully over the course of the day, to keep them loose (it causes short term pain, but feels less painful long term, but I don't know if it might cause damage somehow), or else to keep that part as still as possible to avoid any further injury?

A few quick things

I am heading to bed early, so I won't be late for my flight, so I can't respond to everyone individually. I will eventually do so, just not tonight *G*

* thank you to everyone who commented re: money/dinner costs/budgeting!

* alternating heat and cold helped my shoulder (the heat was especially yummy) and so did the ibuprofen (I think! I hope. I'm packing some extra just in case I need it on the flight *G*)

* much love and kisses. Closing the laptop now to conserve battery; next time I'm online, I'll probably (most likely maybe) will be already in the USA ;-)
