instruction: hi doctor I am 34 years old I have had pain in both of my legs when sitting for about 12 years the pain starts 15 minutes after sitting and it is pretty bad there are itchy and burning pain between my calves and ankles and it feels like my legs are squeezed in this area at the same time there is dull and a kind of bursting pain in the feet and dull and itchy pain in the back and the middle of upper legs nothing in the buttocks sometimes there are tingling sensation starting in the middle of upper downwards it feels like I need to raise my feet a little bit from the floor and move them all the time there was minor varicose vein removed on my right leg no more visible veins there since then and you can see the vein on my left leg but they are not varicose when I stand up it feels like 70 90 of the pain is gone there is no pain when I walk also there is a tingling sensation when I lay down and bend my knees so I feel these sensations from knees downwards it feels like there is a problem with circulation but why it starts straight away after sitting I know some people who have pretty bad veins on legs but they do not have that bad pain like me it drives me crazy please suggest
output: hi leg pain can have so many causes but from your history of aching after sitting suggest a possibility of dot deep vein thrombosis dot is the formation of a blood clot in a deep leg vein blood vessel the pain is typically a burning or cramping sensation immobility is one of the cause of this immobility results in slow blood flow from the leg to the heart slow blood are more likely to clot than normal now you have to consult a surgeon immediately and do a doppler study of both legs to check the blood flow they will provide you with medicines
