My head bumped through a 3ft block of wood about 4 months ago but I have no lump or headaches after that incident. After a week I consulted a doctor because I feel numbness and pressure in my head and found out that my BP is 160/100. He gave me amlodipine and vitamin B complex. I have no damage in my skull after x-ray. Now I feel numbness in my legs, jaw and head. What do you think are the causes of this numbness? I'm 48 years old now and my weight is 60 kgs.
