Starting right now begin soaking your leg (hot spots especially) with hot wet compresses. I sit on the tub seat, put my foot against the far end, turn the water on, soak a towel with hot water, and place it on the leg. Water just drips away down the drain. Use a cup to pour more hot water on the towel as it cools. Feel towel first! It will feel as though it is cool on the leg but your hand may tell you differently. Depends on YOUR water temp to start with.
Keep it wet and hot - - don't burn yourself! - - you will feel that it itches at first but in a few moments that sensation leaves. Keep the compress on for at least 10 minutes. Do this multiple times a day.
Also start taking a regular aspirin for its anti-inflammatory properties. I take a couple a day when the veins kick up.
Actually movement is better than too much sitting/resting. But do try to elevate the leg when sitting.
You can't soak it too much! Good luck. Remember wet & hot compresses.
