I have a bubbling sensation in my left leg - calf/back of

Resolved Question:

I have a bubbling sensation in my left leg - calf/back of knee/lower thigh. I flew from australia last Tuesday and have been sitting for long periods at a conference since. There is no pain. I am due to fly back on Wednesday. Can you give me some advice to relieve this and to prevent possible DVT on my return trip?

Thanks for the input

This seems more like a nerve problem.The nerve supplying the area may be getting compressed somewhere along its course causing the sensation.
But with history of a long flight and prolonged sitting DVT is not improbable and it would safer to get it ruled out by having a color doppler test.
To decrease the risk during a flight some measures can be taken
Keep mobile.Walk every hour or so , keep moving your foot at ankle and leg at knee to keep the muscles working and blood circulating.
Keep yourself well hydrated as dehydration during travel can lead to thickening of blood and increased risk.
Avoid too much alcohol.
Avoid sleeping for long as this causes immobility.
You may also use a compression stocking as this helps prevent DVT.
