I have sciatica and everytime i have heavy pain that part of the body will swollen after, what should i do?

See Spine Specialist: Sciatica is a symptom,not a diagnosis.Sciatica means you have pain down the leg resulting from compresn of the sciatic nerve.The diagnosis is what's causing the compression i.e. a herniated disc.Swelling may or may not be related & needs eval.It could be due to the muscle weakness alone or in combination w/other causes i.e. fluid retention a/f standing/walking long.PT,core training may help this.
