I don't have varicose veins, but my doctor recommended support stockings due to redness in my knees to prevent it. are 20-30 compression knee highs good?

Varicose veins: A mild compression knee high support hose can lessen edema. 20-30 is likely good. More importantly not too tight, put on early after awakening, and check with your pcp regarding the "redness" @ your knee. Phlebitis, cellulitis, diabetes, etc. Can make wearing them difficult.

Yes: You do not have varicose veins and you have noticed redness in your knees. Compression stockings are good for people standing long durations. They are difficult to wear everyday. The redness in the knees may not get better with the stocking so try 1 pair first and if it gets better then buy more.

Yes: Most people tolerate these well for daily use. Good luck!

They are ok: Replace them ecery 6 months.

See vein specialistc: Significant venous disease of the leg often presents with skin changes just above the ankle on the inside of the leg. Compression stockings can help slow the progression if you have vein disease but stockings do not treat the underlying problem. If you are going to wear stockings I would suggest having an evaluation by a specialist in venous disease.

Maybe not: It is usually recommended that 20-30 mm Hg stockings be used, but often thigh-high are necessary rather than knee high. Most patients have venous reflux located in the thigh great saphenous vein, so thigh highs are usually better. An ultrasound documenting your reflux would help decide. Also consider treatment of the reflux with saphenous ablation. Consult w/ a vascular surgeon vein specialist.

Varicose veins: that compression is ok you would do better being evaluated to determine if there is a vein issue. the simplest test is avenues doppler ultrasound. otherwise i am unsure what the stoking will accomplish, if your only symptom is redness around your knees
