It all started from pain/tingling near shoulder blade at back, I took nerve medicine for almost 3 months and now it seem 90% cured. I started feeling my legs tired/heavy 3 weeks ago, left one got normal in a week but right one stays as it is. Nerve med. Didn't make any change. Already taking uprise d3 as blood report said deficiency for vit D3. B12 level is normal. Please guide what could be causing it and which doctor should I consult. Thanka in advance.
