Lip Twitching, Nausea, Dizziness

Thanks for posting your query.
Muscle twitches or fasciculations are small, local, involuntary muscle contraction and relaxation visible under the skin arising from the spontaneous discharge of a bundle of skeletal muscle fibers. Twitching has a variety of causes, the majority of which are benign.
The presence of nausea and dizziness with twitches could indicate the possibility of a endocrine abnormality or an electrolyte deficiency.
I will suggest you to consult your doctor who can order
1. A few blood tests including thyroid function tests,
2. Serum electrolytes including Serum calcium and potassium levels.
3. Serum B12 levels.
In case the above tests are normal, further testing can be done including - nerve conduction studies, Electromyography, etc. These tests might help to diagnose any underlying neurological issues.
The treatment of most of the conditions is very easy and the condition will resolve on its own. In some cases, prescription medications might be needed to stop severe symptoms.
Hope this answers your query. I will be glad to answer the follow up queries that you might have.
Regards.
