Detailed Answer:
Hello!

Thank you for the query.

Can you please attach a photo of it? Have you had any injury of this area recently? Is your calf hard and painful?
From your description (not being able to see it) it sounds like veins thrombosis can be the reason. In such case, the calf should be larger than the other one, painful and hard (lack of this symptoms do not rule thrombosis out). For sure the area where thrombosis is present there should be pain and hardness.
I suggest you to do not wait with it. Please consult your doctor and consider Dopplers ultrasound of leg veins. In case of thrombosis, heparin injections are necessary.

Hope this will help. Feel free to ask further questions.
Regards.

Detailed Answer:
Than please do not wait with it and go to the doctor. If both legs are numb and you really can not move them at all, it is rather neurological problem.
