Ihave a clot in my left leg since 2003 and I would like to know how to get rid of it

"When a blood clot forms within a vein that is located deep in the human body, it is called deep vein thrombosis. Blood clots can typically form when the blood begins to thicken and then form together. Deep vein thrombosis usually happens in the upper thigh or within the lower part of the leg. When the blood clot begins to travel throughout the body's blood stream, it is called an embolus, and it can be a very serious condition. The clot can then block many vital organs of the body, and it is then referred to as pulmonary embolism."

hi pamela.
Throbbing from vascular origin
A vein can produce this sensation because of the increased blood flow to a particular area due to physical activity - this can happened when you jog in the morning or after bodybuilding exercise or any other physical activity. When somebody tackles you during a football game and traumatizes your leg, the swelling can push on the vessels and this can produce a throbbing sensation. A trauma can also produce an abnormal communication between an artery and vein - this is called AV fistula.
Usually throbbing from vascular origin is not a reason to worry. You may visit a general practitioner who will probably examine the blood flow and may even order a test to look at your vessels.
Rarely the cause of throbbing is aneurism which produces a wide pulsatile area - aneurisms are often treated surgically.

• It is useful to know that common conditions such as deep vein thrombosis, blood clots or peripheral artery disease usually do NOT present with throbbing sensation but usually present with pain and swelling.

Throbbing caused by muscle twitching
Turn off the lights, sit on a chair and use a direct light from a lamp and try to make the light beam horizontal so you can see the throbbing area clearly.
If you see tiny twitches you should know that your throbbing sensation is produced by your muscles.
Conditions causing muscle twitching
Although muscle twitches are often idiopathic or as a result of muscle hyperactivity or hyperexcitability because you had too much coffee or you had a heavy exercise earlier, muscle twitches can be a symptom of a serious medical conditions.
B12 deficiency. This is found especially in alcoholics or vegetarians. Muscle twitching is not an early symptom, usually B12 deficiency presents with anemia and decreased or altered sensation.
Multiple Sclerosis. Usually presents with pain behind one eye. Muscle twitching is a common symptom.
infection and Amyotophic Lateral Sclerosis also known to cause muscle twitches. It is advisable to see a neurologist for further evaluation, the neurologist is most likely to order MRI and blood test

Hope this helps :)

one is under the hood next to battery and the other is under the dash above the driver's left leg.

First check the ECM to see what error code(s) it has set. This is done through the OBD-II connector under the dash on the driver's left leg side.
Then post a new question, "What does code _____ mean on a 2003 Tahoe?"

it could just be the under body mud sheld come off, or a wheel bearing on its last legs,,,its a good idear to have it looked at very soon by anybody who knows about cars? not a back street shop?

disconnect battery for 5 minutes and reconnect.
