I felt amphetamine has entactogen-like effects, before even knowing that they were closely related; imagine what someone knowingly ingesting amphetamine as an entactogen might feel. Why are many entheogens and entactogens illegal if they have many benefits and miniscule possible harm? Well, the short answer is for no reason.
Dislocated shoulder. A dislocated shoulder happens when your upper arm pops out of your shoulder socket. The shoulder is one of the easiest joints to dislocate because the ball joint of your upper arm sits in a very shallow socket. This makes the arm extremely mobile and able to move in many directions, but also means it isn't very stable.
This will cause pain in the collarbone but also in the shoulder and sometimes in the upper chest. Bursitis: A bursa is a sac that provides a cushion to joints and muscles. Bursae can become swollen and painful after injuries. Bursitis of the shoulder may cause pain to radiate to the chest. Sometimes the smaller bursae in the chest wall can become inflamed and cause pain. Heart attacks: Although the problem is the heart, heart attacks can cause referred pain to the shoulder or neck.
