Avoid injecting into areas that are noticeably firm or lumpy and allow those areas to recover for at least a few… Go to post

Air bubbles in a subcutaneous injection: the honest risk assessment is low. Tiny air bubbles in subcutaneous tissue do not behave like an air embolism in a blood vessel. A few air bubbles are not a reason to restart the entire injection.
