Question

If pain only exists in the mind, why can't paracetamol or aspirin or w/e get rid of it?

Answer 1

because these drugs only work on the physiological portion of the pain (the type of pain that is actually physically happening like cuts and breaks). Pain is a signal sent from a stimulus up the spinal chord to the primitive portion of the brain which is interpreted as "pain" and associated with the location of stimulus. Drugs only block the signal to and from the brain. if the pain actually occurs in the body it will manifest in the brain, if it originates in the mind (IE phantom pains) there is no signal to block so it will not work.
