[52M] Experiencing numbness and tingling on the right side of the body

What might be happening

Based on the information you've provided, the following conditions might be causing your symptoms:

• Stroke: Sudden numbness or weakness in the face, arm, or leg, especially on one side of the body, can be a symptom of a stroke. Other symptoms can include confusion, trouble speaking, dizziness, loss of balance, or severe headache. Given your age, history of hypertension, and diabetes, you are at a higher risk for stroke. However, you've mentioned that these symptoms have been present for three weeks, which is unusual for a stroke as its symptoms are typically sudden and severe.

• Peripheral Neuropathy: This condition results from damage to your peripheral nerves and often causes weakness, numbness, and pain, usually in your hands and feet. It can also affect other areas of your body. Your diabetes can put you at risk for this condition.

• Sciatica: This condition can cause numbness or tingling in the leg and foot, along with pain in the lower back and hip. However, it wouldn't typically cause symptoms on one entire side of the body.

What you can do

Given the severity and duration of your symptoms, it's important to seek medical attention as soon as possible. While waiting for your appointment, try to rest and avoid any strenuous activity that could potentially worsen your symptoms.

What you should look out for

If you experience any of the following symptoms, seek immediate medical attention:

• Sudden severe headache
• Trouble speaking or understanding speech
• Loss of vision or blurred vision in one or both eyes
• Loss of balance or coordination, or fall
• Sudden, severe numbness or weakness, especially on one side of the body
