Just had my 2nd shot of EQ and I'm feeling like I have the flu. I have never used EQ before, so how long does this flu like symptom last. Also I have knots at the injection sites. Sore and hard as a rock, is this normal for QV EQ? I have plenty of experience with AS so my delivery is safe and sterile, I'm using a 25g, 1" pin 1cc eod 1st to the glute and 2nd one went to the thigh. Any info would be appriciated
