Making the world better, one answer at a time. Angel Dust is one of the street names of Phencyclidine, or PCP. It is a drug formerly used as an anesthetic agent, exhibitinghallucinogenic and neurotoxic effects.
A blow to the rib cage can cause either a fracture or bruising to the membrane that covers the bone (periosteum). Both can be very painful, and it is very often hard to distinguish the difference, even with a X-ray.
Trauma to the ribs can sprain the ligaments that stabilizes the rib cage where the ribs connect to the vertebra (a common problem) or where the ribs connect to the sternum (less common). A sprain can also create scapula pain where the levator tendon attaches. Some neck pain radiates up from an injured rib cage.
