you're experiencing the doms effect (delayed onset of muscle soreness) which is normal. this occurs within 24 to 48 hours after a strength session and can last for a couple of days depending on how many exercises you performed. back off on the initial workload until your body can adapt to the new stress. when you work out lactic acid is produced and released within your muscles. this can last for several days. the best thing to do is to remain active (at a very low to moderate rate until you feel capable of increasing your activity level) keeping your muscles warm and stretched ultimately working out the lactic acid. also keep yourself hydrated. you can use heating pads & ice packs routinely to help increase blood flow to the area to expedite recovery/healing as well as to keep the swelling down. always stretch slowly never exceeding your comfort zone or straining yourself. if pain worsens or symptoms continue seek medical attention. that soley depends on if you're out of shape. if you don't usually work out as much as you have been these past three days then your muscles are probably just sore and getting used to the work out. i don't think so you may have over worked them by trying to excersise too much at one time but if the pain continues then you should go see your doctor about it
