Phlebitis on the legs. please tell me when it will go away?

Several weeks: Phlebitis refers to inflammation in superficial veins, but more generally implies clot in them. This is not the dangerous deep vein clot, or dvt. With appropriate conservative management, including compression stockings, nsaid's, elevation, moist hot compresses, and exercise, the acute symptoms usually resolve within a few weeks, although it may take months for the full clot load to be reabsorbed.

Can be quick or it: Can take months. Often what happens is that the pain, swelling, warmth, redness and inflammation go away but some residual scar is left in the vein. This can lead to further episodes of phlebitis later on, or it might never bother you again.

Thrombophlebitis: I am assuming that you have superficial thrombophlebitis, as this is what is typically referred to as "phlebitis". There is usually a cause, such as varicose vein or venous reflux, so advise that you see a vascular surgeon. Symptoms usually resolve w/i a few weeks using compression stockings, ibuprofen, & heating pad to the area. But recurrence is a problem if the cause isn't addressed, so see MD

Phlebitis: this is usually a symptom associated with varicose veins, with a clot forming in the vein causing an inflammatory reaction with associated redness Of the skin and firmness in the vein. Evaluation with a venous Doppler sonogram Is important to diagnose the location of the clot and its proximity to the deep system. It also identifies if there is evidence of venous reflux causing the varicose veins
