Omeprazole and neurologist

my symptoms were with Prevacid, I believe that these drugs all have the same dangerous side effect. It started with extreme weakness, numbness and pins and needles in my legs and arm. Now after 9 weeks of stopping the Prevacid I feel shaky and tremors. I take b-12 injections because it seemed to have depleted me of my normal b-12 levels. I am hoping this is the problem and will improve . until than my doctor has me going to a neurologist to assure it is nothing else . mri of brain is normal and thyroid is normal. HOW LONG UNTIL THESE SYMPTOMS SUBSIDE , PLEASE TELL ME THEY WILL GO AWAY.
