Hello there,
Do you have twitching in your muscles?
Where exactly do you feel numbness and cold?
Does your leg feel heavy?
What is your height and weight?
Smoking how many ciggrettes a day?
You are a young lad...hence the problem should be detected soon...get back to me with the answer to the above questions so a proper diagnosis and treatment plan can be worked out.
Regards.
