Both my sister and myself have been diagnosed with fibromyalgia. As far as I know, there is no one else in the family with this. Is this a genetic thing or just a coincidence that we both have it? Grandmax2
There is some evidence that genetics does play a role in fibromyalgia. It can run in families, but we are not sure why. More research is being done in this area as we speak, so we may find out the answer within the next few years.
