Yes, some mild tenderness, swelling or small patches of bruising can occur after PRP injections, but this is a normal and temporary reaction. These symptoms typically arise due to the small needle pricks and the body’s natural inflammatory response to stimulate healing. Most discomfort subsides within 24 hours.
You can ease tenderness by avoiding pressure on the scalp, keeping your head elevated while sleeping and refraining from touching, scratching or rubbing treated areas. Bruising is usually minimal and fades quickly. If you experience persistent discomfort, you should contact your clinician, though this is rarely necessary. These mild side effects are part of the body’s normal healing and indicate the PRP is beginning to activate the scalp.
