Acupuncture :

Body parts where acupuncture needles get inserted can feel sore after needles are removed.
Soreness from acupuncture typically dissipates within 24 hours.
Although less common than soreness,
bruising can occur at the needling site.

Acupressure :

Acupressure is an alternative healing modality brought to focus by traditional Chinese medicine,
and also promoted by Ayurveda. Fans of the practice have reported targeted pain relief,
reduced stress and anxiety, and a greater sense of calm and well-being.
It’s also a term that is often confused with or assumed to be the same as acupuncture.
To clear the air, while acupuncture uses needles to puncture certain points of the body
to relieve pain, acupressure adds pressure using the palm and elbow on the same points—no
needles involved.
