Hello @jaaade, I would like to add my welcome along with @parrot53 and others. It's good that you have already started the ball rolling to get a diagnosis with your doctor or care team. I am hoping another member with similar experience with symptoms can share them with you. I did find some information that may be helpful.

"Can neuropathy affect one side of the body?
Proximal neuropathy is a rare and disabling type of nerve damage in your hip, buttock, or thigh. This type of nerve damage typically affects one side of your body and may rarely spread to the other side. Proximal neuropathy is more common in men than in women and more common in people older than age 50."
