Hello doctor,

I am around 20 years old and have had numbness and slight weakness in my legs. Kindly help.



Welcome to icliniq.com.

I understand your concern.

I would like to get detailed information about your symptoms:

1. Is numbness limited to only toes or whole feet?

2. Do you have any pinprick sensation, tingling, burning, or decreased touch sensation over your toes or something else?

3. Is this numbness occurring intermittently or persistently?

4. If intermittently, have you noticed any triggering factor for this?

5. Have you had any lower back or neck pain?

6. How was your sleep cycle?

7. To what extent are you having weakness in the left leg? And what activities are you not able to do?

Kindly revert.

Thank you.

Hello doctor,

Thank you for your reply.

The numbness is only limited to my toes. There is a slight pinprick sensation when I touch my toes. The numbness is persistent, and it never goes away. There is no triggering factor, and I do not have any lower back or neck pain. I had a good sleep. The weakness in my left leg is limited to the extent that I think I might even be imagining it. I only feel that compared to my right leg, my left leg feels slightly weaker, but it does not prevent me from doing any activities. I mostly feel a prickle of pain coming up my left leg sometimes.



Welcome back to icliniq.com.

I would suggest a clinical examination of your condition. Also, I suggest the following tests:

  1. MRI of LS (magnetic resonance imaging of the lumbar spine) and screening of the whole spine.
  2. NCV (nerve conduction velocity) bilateral lower limbs with bilateral superficial peroneal nerves.
  3. Vitamin B12 and D3.

Thank you.
