What to do if you were injured after injection.
I collected some useful links which hope will help you. But it is better to be careful at the begining to avoid all these unpleasantness.
Swelling, redness or increased pain after 24 hours may signal a joint infection. This is a rare adverse effect but needs immediate attention. In more superficial areas, such as "trigger injections" used for localized muscle pain, the skin may thin, or in dark skinned patients, may develop a lightening or hypopigmentation. Other potential but rare adverse effects include, but are not limited to tendon rupture and damage to the bone.
The first advice, massage the area for 2-3 minutes right after injection and throughout the day.
I will give you the link to the detailed procedure on injections. Please read it:
