Pain and tingly leg. Foot twitching. Shake walking down stairs!

I'm pretty young but the past 2 years have shown me to not take life for granted.

Had been denying my symptoms but finally sought medical attention.

My leg is so painful. 

I can barely concentrate. It's tingly and aches all day, especially at night.

Recently my motor skills walking down stairs have dropped, I can barely do it without shaking.

My big toe twitches has lost much strength.

This is all my left leg, which is swollen (2cm larger) with bulging veins. 

The doctors think it's two separate issues.

I need help with the neuro pain though, and how to walk down stairs!!! please.

Wow are u sure u don’t have Gillian Barrie syndrome? To learn how walk down stairs ? What exactly are they saying ? If you have your leg is swollen your veins are in larger tvere has to be a reason more then pain . I have pain bad , bad going through multiple things . How old are you hun? We’re you from . Actually I have pain right now that’s why I woke up ,pain when u have it it’s unbarable sad to say suffering with many things feels exhausting . 

Hi up late because my leg hurts so much.. so original post might be hard to read. I'm 21. 

I can walk down stairs but the last year my legs have started to shake when doing so, it's embarrassing and I try to find an elevator or escalator. 

Yeah left leg's swollen a lot, maybe that is the reason for the pain. Or its nerve damage..Honestly don't know, just need a way to manage this. So much happening.

Sorry to hear you're in pain too. 

Gillian Barrie syndrome, will research more.
