Detailed Answer:
Dear XXXX,

Thanks for your query.

Regarding the sensation of numbness in lower lip, kindly let us know about the following:
1. Any episode of recent illness?
2. Any history of injury or trauma to the lower lip or head and neck region?
3. Involuntary twitching of muscles can be due to neurological damage secondary to Hypertension & Diabetes (known as Hypertensive neuropathy & Diabetic neuropathy respectively).
Is there is significant past history of systemic disease like Diabetes, Hypertension, Thyroid disorder, etc. ?
4. Any recent history of Stress, inadequate hydration, improper nutrition & lack of sleep?
5. Habit of smoking or alcohol consumption?
6. Any other associated features like inability to concentrate or remember things, dizziness, visual disturbances, nausea, etc.?
7. Any history of prolonged intake of medications?

If your answer to the above mentioned questions is NO, then the symptoms can be attributed to inadequate hydration status & electrolyte imbalance of the body or dietary deficiencies of certain nutrients like Iron, Calcium, Vitamin D, Vitamin B 12, Folic acid, etc. which help in blood formation & nerve conduction.

Symptomatic relief can be obtained by intake of nervigenic agents as well as multivitamin & multimineral supplements including iron, calcium & Vit D needs to be added in your diet.

In your post, you have also mentioned regarding checking of blood pressure and blood sugar.
Please let us know about their values.

Wishing you a Good Health.
Please let me know if I need to clarify further.
Take care.
