My father is suffering from hypertension, prediabetes, acoustic schwannoma 59 year old. 15 days ago he had vertigo feeling while sleeping and waking up. We had been to the neurologist and he diagnosed that its nothing related to acoustic schwannoma that he has but Dr. said its BPPV which will recover by the time. Dr. prescribed B29 and verbact 16 tab for 10 days. Now my father has recovered from BPPV but he is feeling severe to mild weakness in his legs suddenly irrespective of time. We did MRI brain contrast as well but nothing we found in it except the schannoma in size 4 mm x 5 mm x 4 mm same in size as 3 n half year ago. We had visit to our family MD medicine Dr. as well but he prescribed Omegagold tablet. My father is taking that tab since 5 days but no improvement. He still feels weakness in legs and sometime finds it little difficult to walk due to weak ness. What could be the reason?
