<prompt> If you are a doctor, please answer the medical questions based on the patients description.hi i have chiari malformation and i want to know if i can use medical marijuana instead of going to pain managment or narcotics and if its gonna affect my condition, i hVE TWO WEEKS TO DECIDE IF I WANT THE SURGERY TO BE DONE BUT I HAVE FOR KIDS UNDER AGE OF 6 TWO AUTISTIC SO I DONT KNOW WHAT I SHOULD DO IF HAVE THE SURGERY OR JUST STAY LIKE THIS??  <response>: its a perfect question. Frankly theres a slight concern on everything including over the counter ibuprofen on its effects. Increased intracranial pressure... certainly occurs with narcotic overdose, not so much on usual doses. If theres build up of co2 from not breathing, then intracranial pressure increases.diam ox may be useful in testing whether surgery might work...this is a controversial statement and flow studies are probably more often used. Marijuana... is not a pain Chat Doctor. There is one 1 report of a possible interaction between Chiara and marijuana to produce psychiatric illness, but you cant really say if the marijuana didnt do it all by itself some people not most, not common with Chiara have neurological deterioration that the surgery would prevent slowly progressing over time from increased intracranial pressure.
