Hard purple lup on knee with redness around. Have had leg pain for a month the lump just showed up. Is this dvt?

Superficial: I sounds like a superficial vein with pain, called thrombophlebitis which is an inflammation of the vein. Other possibilities include an infected cyst or hair follicle, or insect bite. It is hard to say without seeing the lesion. Best course of action. Apply a warm compress for about 5 minutes, multiple times and take an anti inflammatory for pain. See a Doctor as soon as possible ...Read more

Get it looked at soon as getting on the antivirals for it sooner would give a better outcome. If, of course, it is shingles. ...Read more
