at a well known high street chemist. Had it every year for years, felt the usual nip but as the chemist (male, big chap versus usual small woman) leaned over to administer. he put it in and pushed the end of the needle to dispense liquid there was a really high pitched air sounding squeak. Neither of us said anything. AIBU to think I might die from an airlock? Not usually paranoid but Dr google says it’s in the right place in muscle and Dr google also that I might have trouble from it. Help me pls medic people 🤷🏼♀️
