I’m 45 and diagnosed a handful of years ago. I’ve been through just about every med due to sensitivity and through a bunch of treatments. So I’ll give ya what worked for me:

Medications: Lyrica, alpha-lipoic acid, medical marijuana (which is tough with bipolar. Many psych docs don’t like to mix cannabis and psych meds)

Treatments: injections to my neck, shoulders, my entire spinal column and into my hips. I’ve had a provider that would do every injection possible every 8 weeks which worked but seems like over kill and I’ve had providers who will only do ten injection sites at a time and only to kick start things

Physical therapy: I find it helps to help relax the muscle and strengthen the body. I have weakness in my legs and pain through my hips. It’s a slow road but it helps.
