im a 20 year old male who was given prednisone to reduce the inflammation around my spinal cord in my neck from a herniated disk. 60MG in the morning for 4 days and 40MG in the morning for 3 days...... no real weening process which im seeing probably should have been administered. while i was on it the mood swings were nuts and i noticed feeling muscle weakness and joint pain along with the occasional burning or tingling. ive been off it for 6 days and now the muscles in my legs and feet twitch and im still crazy in the head with little sleep and sinus headaches that don't quit. how long does this shit go on?
