Generally, physicians like to "deal with one problem at a time".
You should tell the doctor your "chief complaint" in your own words, without using medical terminology. In the case of your leg, you should be prepared to inform the physician when the problem started (a time line), whether or not it changes from hour to hour or day to day, and if there is any pain or discomfort.
There are many possible reasons for the swelling, some serious, some not so serious. In some cases the problem is dealt with by treatment as simple as an elastic stocking and elevating the leg at night. In other cases medications called diuretics may be necessary to remove fluid. Or, you may be referred to a vascular specialist for further evaluation.
This is a common problem and most physicians will be able to select the appropriate tests and provide a diagnosis and treatment. There is no reason you should not be able to continue work, although usually standing up all day is discouraged.
This is not a 911 call, but you should arrange an in-person evaluation by a physician at the earliest opportunity.
Hi
Welcome to the MedHelp forum!
A single leg can swell in rheumatoid arthritis, deep vein thrombosis, lymphangitis (inflammation of lymphatics), thrombophlebitis (inflammation of vein with clot), trauma, fracture, ligament tear, tendonitis, bursitis or ankle strain. It can also be due to localized infection of the skin. You may need duplex ultrasound or color dopplar to rule out deep vein thrombosis, lymphangitis and thrombophlebitis, or MRI, X-rays and other tests.
Make a note of your symptoms, the order in which they appeared, possibility of leg touching something and starting an allergic reaction, insect bite etc. Do discuss this with your doctor and get yourself examined. Take care!
