Ethernet now commonly uses a star topology,although this is rather unfavorable when it comes to system wiring and canlead to excessive cabling effort or highly cascaded communication depend-encies.Another factor is that not all Ethernet installations are identical.
A cervical selective nerve block is an injection designed to help relieve neck pain, shoulder pain, and/or arm pain caused by a pinched nerve or nerves in the cervical spine.
Doctor suggested cortisone injection and on July 13 I had a shot in my shoulder. The pain lessened. I had been doing physiotherapy for 9 weeks before and after the shot. However I was at work and had to hop up over a small counter top. My life has been a severe painful nightmare since then. The pain I've been experiencing since that day is unbearable. I was not told that cortisone weakens the tendons in and around the area of the injection. The doctor gives me strong pain killers but they have side effects that I'm looking forward to.
