Let’s go over some of the possible causes of this situation that may be understandably distressing you.

Uncontrollable Tremors

If you have a tremor, then that in itself is also a symptom of a condition that you could have, and that results in leg shaking. The causes of tremors can be a stroke, multiple sclerosis, Parkinson’s Disease, brain injuries, or any traumatic brain injury which you will need to have evaluated. If you have kidney or liver failure, that can also cause tremors. Either way, you need to have the situation evaluated so you know why you have the tremor.

Restless Leg Syndrome

A common cause for your shaking leg would also be restless leg syndrome or RLS. That is characterized by an uncontrollable urge to keep moving your legs. However, the movements you have from RLS are voluntary because you have a lot of discomfort in your legs. There are several treatments for RLS.

Tardive Dyskinesia

If you are taking medications for mental health disorders such as schizophrenia or for gastrointestinal issues, the medications can cause tardive dyskinesia which is a condition that causes involuntary movements throughout the body, including the legs. It is due to changes in the brain chemicals that can cause this issue. The only solution to this problem is to find another drug that will not cause it.


Anxiety will cause a lot of shaking and other involuntary movements as you end up in a fight or flight space. Therefore, you can suffer from tremors and if your anxiety is chronic, it can result in tremors that cause a lot of shaking. The best solution is to practice relaxation techniques such as meditation.

Dementia And Alzheimer’s

If you think of dementia and Alzheimer’s disease, it is a lot more than behavioral issues, memory loss, and cognitive decline. You have to remember these age-related diseases are the rest of the damage to the brain that is progressive. Therefore, you can also be facing ailments that involve leg shaking and uncontrollable tremors.


When your thyroid is too active and you are losing weight without trying, and at the same time you are hot all of the time, that also can cause leg tremors and that is because the body is speeding up. You will need to get checked for your thyroid to see if that is the cause. You may potentially have Graves disease which is an overactive thyroid disorder that is autoimmune. You may have shaky legs, arms, or any type of restlessness as well as anxiety. There are treatments for this condition.

You can also end up with leg shaking if you are drinking too much, taking stimulant drugs, or if you have uncontrolled diabetes which would result in neuropathy which is nerve damage. Either way, if you cannot stop shaking your legs, you need to see your doctor so they can rule anything out and find the cause. Most of the time, a cause for this will be discovered but once they are able to treat it, they can help you and your leg shaking should calm for the most part. That also depends on the cause of it too. It may not be able to stop completely but if you know the cause, you will feel better by understanding why.
