Possible Isthmic Spondylolisthesis?

Hello, (24, F)
I have experienced a complex set of symptoms since childhood, many of which have persisted or worsened into adulthood.
My key symptoms are:

- Chronic muscle tension throughout body, mainly affecting the thighs, calves, shoulders, buttocks, lower back and jaw (TMJ). These symptoms often cause frequent “knots” especially in lower back.
- Pain when pressure is applied to lower back around the spine.
- Occasional sharp pain that radiates throughout lower to mid-back as well as the thighs and buttocks (possible sciatica).
- Back stiffness with having the constant urge to “crack” and or stretch it.
- Sitting on hard surfaces (e.g: wood, metal and hard plastic) for a certain amount of time will cause numbness and eventual pain in the buttocks.
- Calluses on both feet in the same place that gradually developed over the course of several years throughout childhood.
- Numbness in right toe next to the pinky toe that will occasionally impair my ability to walk, causing excessive pain regardless of type of footwear and or changes to gait.
- Uncontrollable tremors in both hands/arms when pressure is placed on either foot.
- Nystagmus triggered by pressure on top of head when lying down (only applicable if eyes are shut).
- Non-painful muscle spasms/twitching continuously throughout entire body at random.
- Brain fog, struggling to communicate and offer stuttering/stammering on my words.
- Visual snow syndrome (self diagnosed).
- Hyperacusis (self diagnosed).
- Urinary incontinence with impaired bladder control, recurrent urinary tract infections, and suspected urinary retention.
(History of incontinence as a child with bed wetting and frequent accidents during primary/elementary school.)
- Frequent (almost daily) migraines/headaches.
- Photophobia (light sensitivity).
- Non-restorative sleep, never feeling refreshed or fully “awake” regardless of how many hours of sleep I receive (I usually sleep between 8–10 hours a day).
- I struggle with the ability to fall asleep spending anywhere from 30 minutes to an hour experiencing restlessness.

Notes:
I first noticed symptoms during early childhood, I would often “complain” that my back hurt and would frequently ask for assistance by getting others to check my spinal curvature (I believed I may had some form of mild scoliosis and that my lower lumbar spine was curved outwards).

My family has had a history of back related issues confirmed by 5 people, their symptoms include:
- Sciatica (numbness, tingling and pain)
- Back pain
- Urinary incontinence

Possible diagnosis:
- Herniated disc
- Lumbar lordosis (personal observation).

I received a diagnosis of idiopathic hyperprolactinemia (mimicking PCOS-like symptoms). My doctor believed that I may had prolactinemia (adenoma tumour) but a CT scan ruled it out.

Suspected conditions:
- Lumbar lordosis
- Spinal stenosis
- Tethered cord
- Spinal cord injury
