• Arrange for the area to be rested for the first 24–48 hours

Frequently asked questions

Does it hurt?

Discomfort is usually brief. Where suitable, local anaesthetic reduces it, and image guidance minimises tissue trauma.

How soon does it work?

This depends on the agent — anti-inflammatory (corticosteroid) effects are often felt within days, while regenerative injections (PRP, dextrose) act over weeks.
