When I was diagnosed in 1989 I asked my Dr if it was genetic and was assured that it was not. .10 years before I got back to normal. and off steroids
2 years ago It started up again and within 6 months my eldest daughter who is 46 years has also been diagnosed with PMGCA too
Asking again I find that it can be genetic.
I am beginning to get better after 2 horrendous years but my daughter is still very poorly.
