I bleed when I inject too far, or if I hit a capillary bed. When I hit a cap bed its ALOT of blood. it rolls down my arm, leg, or wherever I poked.

I used to winch and wait for the IPIR as its more likely if you clip a vein, but when it didnt come, I started to not be so panicked over it.

If your using an AI adjust the setting to less. After the injection PUSH straight into the area. DONT RUB! copaxone is a sharp crystal type med, and rubbing it breaks open the crystals. just PUSH firm hard pressure for 15 to 30 seconds. it pushes the meds from the upper layer of fat to the deeper layers. it was a miracle for me.

try ICE before hand. ICE will shrink those blood vessels and make them less of a target. It will also help with pain control. Some times SS says to use heat before, but I always found I bled like crazy.

DONT do it right after a hot shower. or use ICE before hand.

good luck.
