Aspiration may and usually does contribute to PIP. If there is a possibility that you may make an intra-arterial injection, then you may feel safer with aspirating. But even then there is no medical evidence to support its benefit or necessity. I make all my injections in glute and soon in ventro so I'm not worried about intra-arterial. It is cumbersome to aspirate in these positions for me. Because modern medicine tells me I don't need to, I don't. If it makes you fell warm and fuzzy inside when you aspirate, then go ahead. I'm just trying to minimize PIP, so I don't aspirate, ever.
