I have my chest tube wound its been three weeks it's still painfull around the area it's oozy but not smelly should it be started to heal abit better?

Chest tube: If the tube has been out for 3 weeks - its a little too long for the wound to still be open. Persistent drainage can be a cause , infection , poor nutrition etc.-see surgeon. Chest tubes are painful you should probably take an NSAID like zipsor (diclofenac) 25mg q 6 or 8 hrs with food, may add ultram(tramadol) 50mg q6hrs for better effect. Nycynta(tapentadol) 50mg q4hrs may replace ultram.

Wound care +: How quickly a wound like that heals depends on how well nourished you are, why you had the chest tube in the first place, and what sort of wound care you're getting. That said, by 3 weeks it should not still be "leaking" fluid. See your surgeon or pulmonologist and have them take a look.
