I am a 34 year old female. I had sciatica one year back . I was treated with metacoblamin tablets for one month and had injections for one week. This happened in Nov. In April I started to have partial focal seizures. Is the seizures something related to the sciatica pain. I had pain on my left leg but the partial seizures come on my right had, leg and face. I had never had seizures before. My MRI is normal. Please do advice.
What is the cause of sciatica in your cause, is there a disc bulge leading to nerve root compression? I there an MRI spine evidence for it? If yes then focal seizures can be an incidental finding not related to sciatica.  But I doubt if you are having true sciatica as methylcobalamin alone with few injections is not the right treatment for sciatica pain.  Both sciatica like pain and focal seizures can be a symptom of same pathology in brain. Even if MRI is negative you should visit a good neurologist for right opinion and treatment.
