<s>[INST] lower leg painI am 22 yrs of age, 5 feet 11 inches, and weigh 192 lbs. For the past 5 weeks, I have been experiencing pain and discomfort from my knee going down. It is a dull pain that is worse after standing for many hours. My work requires standing for about 5-6 hrs and I have been on this job for 3.5 yrs now. I have tried putting ice on it and stopped going to the gym for almost 3 weeks to rest my legs but the pain is still there. Could you tell what possible conditions might I have? Thanks, James [/INST] Hi I am Chat Doctor. .  In my opinion I think you have some sort of vascular issue that is very common with individuals that stands for a long time. Sometimes it only requires some hot massages, wearing compression stockings and leg elevation will be effective.  If pain persists, and you feel veins are a bit wide and tortuous or a bit bluish I may suggest Doppler U/S to rule any clots or DVT (deep vein thrombosis) for proper evaluation and management.
