Vitamin D +Vitamin b12 deficency. Here?

I was diagnosed with vitamin D3 deficency in Feb ,had strange symptoms like internal body vibration(tremors) , sudden numbness in hand and legs, burning sensation in palm and feet , bubbling sensation at random body parts like shoulder and back, grinding sensation at left knee joint ,joint n back pains. Though I feel better now but vibration are still there n it's external now very mild but it's there while holding a pen or any object I can sense that.Currently,on medication for Vitamin D3 n B12 it's been 3 months now. Between  mid Feb to mid march I took 4 injection Architol 6L (1/week) but due to lockdown couldn't continue. Minor improvement was there but in Mid April started feeling low and experience symptoms again so consulted another doctor whose medication I'm currently on. It's been a month now how should ai go forward from here? As this mild external tremors ,mild burning sensation in palm n feet are keeping me worried always. (Note - I have cerebral palsy by birth)
