Numbness in legs lethargy. Advise.

I am encountering problem with numbness in both legs, feel lethargic and fatigued throughout the day. Even if get a proper 7-8 hours of undisturbed sleep this problem is continuing. I have a feeling that somebody keeps massaging my legs and feet. After consulting with doctor have taken vitamin D and calcium but of no relief. Have tried with acupressure and ayurvedic therapy but that is also of no use. This feeling of fatigue and tiredness is affecting my confidence, I have kind of stopped socialising, I have started avoiding meeting friends as I feel like getting back home and relaxing. I have been a sports person and actively played Cricket, Soccer, Hockey and even adventure sports like river rafting, trekking etc. But these days going to work is a tough task. Please advise.
