Dr. Zakia Dimassi Pediatrics
To answer your question, I'd like to know your father's age, previous medical history (any chronic diseases like diabetes, hypertension, cardiovascular diseases), any previous surgeries (open heart surgery, cardiac cath...), any medications he's currently on, associated symptoms like dizziness, blurred vision, headaches, weight loss, fever, family history of serious illnesses. Thank you.
Dr. Rania Mousa General Medicine
in general There are many possible causes of numbness and tingling:
Sitting or standing in the same position for a long time
Injuring a nerve (a low back injury can cause numbness or tingling down the back of your leg and somtimes to the feet)
Pressure on the nerves of the spine, such as from a herniated disk
Pressure on peripheral nerves from enlarged blood vessels, tumors, scar tissue, or infection
Shingles or herpes zoster infection
Lack of blood supply to an area (for example, from atherosclerosis or frostbite)
Other medical conditions, including:
Multiple sclerosis
Transient ischemic attack (TIA), sometimes called a "mini-stroke"
Underactive thyroid
Raynaud's phenomenon
Abnormal levels of calcium, potassium, or sodium in your body
A lack of vitamin B12 or other vitamin
Use of certain medications
Nerve damage due to lead, alcohol, or tobacco
Radiation therapy
Animal bites
Insect, tick, mite, and spider bites
Seafood toxins
You should find and treat the cause of your numbness or tingling.For example,If your father have diabetes, your doctor will discuss ways to control your blood sugar levels.
Go to a hospital or call emergency if:
You have weakness or are unable to move (paralysis), along with numbness or tingling
Numbness or tingling occur just after a head, neck, or back injury
You cannot control the movement of an arm or a leg or you have lost bladder or bowel control
You are confused or have lost consciousness, even briefly
You have slurred speech, a change in vision, difficulty walking, or weakness
Call your doctor if:
Numbness or tingling has no obvious cause (like a hand or foot "falling asleep)
You have pain in your neck, forearm, or fingers
You are urinating more often
Numbness or tingling is in your legs and gets worse when you walk
You have a rash
You have dizziness, muscle spasm, or other unusual symptoms
