Since a long flight a week ago, I have a pain in my calf that is intermittent and the vein is apparent, but the calf is not red and not swollen. I wonder if it would be better to consult. Thank you for your help.

It is important to consult a doctor to get the right diagnosis for your symptoms. Thrombophlebitis is a condition that can cause pain, numbness or cramping, heat and swelling, and it is important to rule this out. Please seek medical advice as soon as possible.
