Phlebitis
My MD just diagnosed this in my right leg, condition is in a superficial vein, leg slightly swollen, very slight reddening in skin, good pulse in foot, ultrasonic scan shows no problems in deeper veins/arteries (nice flow and flexible walls) so says not serious - but it hurts.
Treatment is oral anti-coag., thrombosis cream, massage with NovaFon unit, damp warm compress.
Anyone had this and how long did it last ?
