MRI sounds like a good start. You are lucky to get one - but be prepared for the noise emitted by thar machine! Hope they provide you with noise cancelling earphones!

Have you ever taken one of those genetic DNA blood tests? Apparently they give one a lot of information on what you are predisposed to. I haven’t taken one because here you need a doctor’s referral even though it is not covered by our health plan - because my doctor doesn’t think it is necessary. 🤷🏼‍♀️
