Had an im shot 5 days ago at weight loss dr in deltoid. bruised & numbness in area?could it have been injected incorrect & cause nerve damage?

Sterile Abscess?: People can get sterile abscesses after IM injections no matter how good the shot is given. I suspect this is the likely explanation. Warm moist heat could help but don't hesitate to be examined for confirmation.

Possible, unlikely: Most likely thing that occurred is swelling that's impacting the nerve. Swelling is common from iintramuscular injections. It is possible a nerve was struck, however permanent damage is unlikely. There is no specific treatment or therapy to be recommended- ice may be helpful medications such as Tylenol (acetaminophen) or ibuprofen may help symptoms otherwise it just requires time. Hope you feel well again soon.

See below: That is a common location to get an injection. It is not uncommon to get bruising. If some of the sensory nerves under the skin were involved then you could also get numbness. The good news is that this usually improves within 2-3 weeks.
