Cupping therapy might have a few drawbacks/side effects. For starters, it can leave marks on your skin that take time to fade or even cause scarring. If not done right, it may result in burns, infections, or worsen skin conditions like eczema or psoriasis. Some rare but severe side effects include bleeding in the head after scalp cupping or anemia from blood loss after multiple wet cupping sessions. Additionally, people might experience pain or discomfort during the procedure, and it may not be effective for everyone or every condition, so it's essential to consult a healthcare professional for personalized advice.
