Tremors in hands, weak legs, dizzy, some numbing/tingling in hands and feet, weight loss. got mri, no ms. is it als? parkinsons? it's not anxiety.

Could: Be. However a neurologists can easily diagnose Parkinson which may present pill rolling tremors with bradykinesia and rigidity . If ever on anti psychotic the EPS could also be considered

Tremors: With these symptoms you need to see a good diagnostician and I would start with my family doctor. He will probably start with a complete blood panel and exclude all metabolic disease . If this is all normal that he will be able to send you to the appropiate specialist to treat your condition. Do not try to self diagnose.
