one of the reasons i had cat scans of the chest for 3 years in a row and now every other year is because i have numerous lung nodules. they are keeping an eye on them to see if they grow or more develop. they are also keeping an eye out for sarcoidosis being that i have the nodules. the group i am in has 10x the rate of sarcoidosis as would be expected from the same age groups in the general population.
im surprised they could diagnose you so quickly with sarcoidosis. for most of the people i worked with it took a while. have you had a lung biopsy?
because a person has sarcoidosis in one organ such as lungs, eyes, etc doesnt mean that the other organs are affected. so if you have it in your lungs doesnt mean that it is causing damage in your nerves.
