the other shoe might have just dropped -worried

I have  had such an excellent recovery that I have felt like it was too good to be true.  Yesterday though my right arm felt very tender and more swollen than the other.  Today it is all of the sudden draining a good bit and is red all around the area.  I took a couple of pictures and emailed the office plus left them a voice mail telling them I emailed.  I haven't heard anything yet and this board is so informatative I thought y'all could probably tell me what you think is going on.  an infection?  If so, what happens next?  I think my deepest fear is that I somehow ripped everything apart in there by doing too much.  Do they just give you antibotics or do they have to open you back up if you have an infection.  worried. 

usually its antibiotics....you did the right thing, sending a pic to the doc...I got a quick response from mine that way..he was a 2 hour drive away...

if you dont hear from them soon call again until you reach someone!!!

and do take it easy your healing!
