What can I take to help with nero fibroma tosis?

Neurofibromatosis. Neurofibromatosis type 1 and 2 are conditions caused by genetic reasons. Unfortunately, there is nothing you can take for these conditions. Treatment is only symptomatic, meaning if you had a tumor affecting your vision you can get a surgery and if you had seizures you can take anti-seizure medications.
Depends. Other than cosmetic disfigurement, treatment depends on what it does to other tissues or organs.
