Go to a different labcorp. In my area, I can go to 4 different labcorps within 10 miles.
I have had at least 50 blood draws with no problems, most of the time it's the same phlebotomist as that labcorp is only 3 miles from my house. I usually go around 10:00 AM on weekdays.
Rarely, it hurts more than usual, like 1 out of 20 times.
Also, with most lab draw orders, I don't actually have to go to labcorp, other labs honor the same order. I have taken ACL blood test orders to labcorp ,though i have never tried to take a labcorp order to ACL It's worth asking if you want to change lab draw sites.
