Is it safe to take an 11-hour flight if I have a superficial blood clot in one of my legs?

I have some redness and bruise-like pain (only on touching) on the front of my lower left leg. These symptoms are occurring near an area of varicose veins. I've been told I have a superficial blood clot that will resolve itself with elevation, NSAID cream, etc. I need to take an 11-hr flight in less than a week with return 14 days later. Is this safe? Should I wait until redness (less than 5cm) is completely gone? I did back and forth 8-hr flights 3 mos ago.

Wear compression hose above or below the knee depending upon where the clot is. Ensure they are correctly measured and fitted and of 20-30 mmHg pressure. Stay well-hydrated and get up and walk often. Do the exercises in the flight magazine. Take an aspirin (81 mg) daily if your doctor allows. NSAID cream won’t do too much but may feel a bit better.

The treated leg itches a lot, specifically down the center. I removed the badges and am wearing the support knee-high compression stocking, but the itching feels like it's under the skin. Is this normal?

I'm obese and post-menopausal. On the front of my left upper thigh, I have 4 small rock-like bulges that are in a straight row. At times they burn and ache; sometimes they are larger than other times. I take cool showers when they burn. On my right leg (outer upper thigh), there has been a small bulging purple vein that itches bad and looks like its leaking. That area also goes numb, yet still itches. I scratch trying to satisfy the deep itching below the numbness but fail to reach it.
