Megan's shoulder take 2!

I am very frustrated with the results of Megan's appointment with the allergist.
The allergist ordered quite a bit of lab work so we went to the lab that they directed us to in an attempt to get her blood drawn and to see if the clustering of histamines have spread to other areas in her body.

Lab #1
Dug around in her arm without any luck. They told me as they were digging around that the needle was probably larger than her veins. My thoughts....why are you even trying then!
They decided that they weren't able to draw her blood and after giving us the materials we needed to collect her urine for 24 hours they sent us to lab #2.

Lab #2
Waited for 35 minutes as other people were getting called back (they arrived after we did).
Finally someone came out to let me know that the allergist had ordered to many labs to be drawn on a child of Megan's size. The lab had called the doctors office and requested a call back so they could decide what labs to draw first and which ones we would have to come back for. The office called back 1 hour and 30 minutes after the lab called them.
We were finally pulled into the back room and they put Megan down on a table. They searched her arms and hands for a vein that would work and could find none. Finally they decided that they were going to try to get at least one lab done by doing a heel poke....no luck there either!

What now?
We could go to the lab in the emergency room where they might be able to find a vein to draw the labs (where we would also have to pay a co-pay...and don't at the other labs).
I have decided to wait until I talk to the allergist and get his suggestion.

My poor kids!
Megan's appointment was at 9:45 a.m.
We went straight from there to lab #1. We left lab #1 at Noon
Got to lab #2 at 2 o'clock and arrived back home at 5 o'clock
Our feeding schedule was off, our sleeping schedule was off, and our frustration level was elevated!
