Hello doctor,

I have a question about twitching in my legs.

Hello,

Welcome to icliniq.com.

Muscle twitching can be related to differential medical disorders:

  1. Neuropathy (nerve damage)
  2. Thyroid gland dysfunction.
  3. Electrolyte imbalances.
  4. Muscular disorders.
  5. Epilepsy (seizures) or central nervous system disorders.
  6. Benign fasciculation syndrome, etc.

For this reason, I would recommend consulting with a neurologist for a physical exam and performing some tests:

  1. A nerve conduction study.
  2. Thyroid hormone levels.
  3. Complete blood count.
  4. Blood electrolytes.
  5. Vitamin D levels for possible deficiency.

Further tests may be needed. You should discuss with your doctor on the above tests.

Thank you doctor,

Do you think it is ALS? I am really scared about this.

Hello,

Welcome back to icliniq.com.

As you can see, there are a lot of disorders that may mimic such symptoms. For this reason, it is important to perform the above-recommended tests.

Nerve conduction studies would help exclude ALS (amyotrophic lateral sclerosis) or neuropathy.

I will be glad to review your tests as soon as you can upload them.

Hello doctor,

I went to my PCP today and he did some tests on me.

Hello,

Welcome back to icliniq.com.

I agree with your physician that a normal physical exam can help exclude a lot of disorders. But, I would recommend performing thyroid hormone levels, vitamin B12 and vitamin D plasma levels, and blood electrolytes to exclude any possible metabolic disorders.

I would also advise performing nerve conduction studies just to be sure that everything is alright.

Thank you doctor,

You think he would have told me if he thought it was ALS, right? Sorry, I have really been worrying myself to death.

Hello,

Welcome back to icliniq.com.

  • ALS patients have a lot of other symptoms and an abnormal physical exam. So, I agree with your doctor that there is nothing to worry about.
  • Anyway, I would recommend performing the above-mentioned tests, just to be sure that everything is fine and definitely put your mind to peace.

Hello doctor,

I had the EMG done. He said it was normal. He did not give me the results, just a paper that said I was fine.

Can I put aside my fears from a neurological issue? I am still trying to figure out how to stop these twitches. He insists it is BFS.

What do you think? Can I trust my EMG results? It was done by a different doctor whose specialty it was.

Hello,

Welcome back to icliniq.com.

  • Thank you for the additional information. I am glad that the EMG resulted normal, as we can definitely exclude ALS or neuropathy. It does not matter if the test was performed by another doctor, because this is a reliable test for these disorders with a high sensibility and specificity.
  • Anyway, I would also recommend checking vitamin D and vitamin B12 plasma levels, coupled with thyroid hormone levels, in order to exclude these metabolic disorders, which may trigger this clinical scenario.
  • If these tests result normal, we can discuss about the treatment.
  • Anyway, you should know that treatment in case of benign fasciculation syndrome is not always effective and it should be started only in cases of continuous and generalized fasciculations, which interfere with the patients daily activity.

In this regard, Carbamazepine or Clonazepam may be started by your doctor.
