I have vericose veins on my left leg. any tips on how to make the pain less because it pains a lot :/?

Compression stocking: Single sided vericose veins that cause pain may be treated by compression stockings as first therapy. If you find relief they should be placed first thing in the morning when you wake up. If you don't find relief or have tried them before then ablation or surgery may be an option. Find a surgeon with experience in venous disease. A vascular surgeon.

Stockings: Medical grade compression stockings (properly fitted and measured) can provide decent relief of vv symptoms. Try them for 90 days and then see a vascular surgeon.

SUPPORT STOCKINGS: The initial treatment would be support stockings either knee or thigh length depending on the location of the varicose veins. The best treatment would be a venous ultrasound to look for malfunctioning saphenous vein valves. Varicose veins are usually due to these valves and they can be treated with a special laser without the need for surgery.

Try compression hose: A simple thing, such as compression hose can do the trick. The compression created by the hose cause the veins to retract and the little walls inside the veins to allow for adequate blood flow.

Compression & treat: Varicose veins may be treated by compression stockings as first therapy. If you don't find relief or want a more permanent solution then see a vein specialist, aka phlebologist about other options. After an ultrasound to evaluate any underlying causes he may recommend saphenous vein ablation, phlebectomy and or sclerotherapy for more definitive treatment.

Non-invasive tx : Besides graduated compression as everyone has mentioned, there are some other things that can be done. Avoid standing for long periods of time, elevate your legs as much as you can, get regular exercise, lose weight if your bmi is too high, and take anti-inflammatory medicine. Ice might be more helpful than heat and is worth a try. Most of all, do see a vein specialist.
