Idk if this is normal or not 😶

But I've been experiencing a weird vibrating sensation on my back. It lasts for about 20 minutes or more. Especially when I get in the shower and just through out the day. It doesn't spread to any other part of my body. I've been having my husband massage me, but it always returns again. I'm getting concerned because I don't know how to get the weird sensation out. I'm debating on whether to call my OB or not.
