My son has raptured an artery on his brain, between the brain and the cerebral membrane. Doctors put him in a coma and for 2 weeks, and only after the third week he regained his conscious. After 5 weeks in ICU, they transferred him to a rehab to learn how to eat, swallow, etc. His left side was lame, but he started using the arm and leg. He has been discharged out of rehab on Friday, but is still very much off-balance. What I want to know is: Can he take the R29 Theridon Vertigo drops for the balance?
