Hey, I totally forgot about this and didn't even see it until just now. I've actually considered the possibility that my numbness was the result of sciatica; however, my doctor feels that is not the case since I now have numbness in my arms as well, but my only problem with his theory is that my numbness in my arms didn't show up until after I visited the chiropractor, so I'm thinking those symptoms aren't related. For the longest time all I had was the numbness in my legs, so I'm thinking that sciatica is a definite possibility, but my doctor says he disagrees. Also, no, I haven't had an MRI of my Lumbar spine because my doctor believes he'd be wasting my time, so I don't know. I'm not a doctor and although my health is important to me I feel like I need to respect his professional opinion too. I'm just sort of on the fence about whether or not I should get a Lumbar Spine MRI. My doctor said he'd do it if I really wanted him to, but he felt like the answer wouldn't be there.
