So here is the deal, 'Chiropractors Are Bullshit' , sure they might fix an ache or pain, but your body will slip back into that state. That is why you need to go for regular relalignment appointments.
Also, Chiropracty caries lots of risk, stroke, pinched nerves, broken/cracked/chipped bones and the list goes on. A family member of mine was in a car accident and had a messed up neck, so they went to the Chiropractor. Next thing we knew they were on the way to the emergency room with the symptoms of a stroke. The adjustments tore and artery in the neck which lodged in the brain, causing irreversible brain damage from the clot.
I sit in a chair all day like you, and messed up my back. I was in PT (physical therapy) for two summers trying to get better, but I still had chronic pain.
What finally helped?
Core strength, exercising, moving.
Now, 3-4 times per week I exersise. 20-30 minutes of cardio, followed by 30 minutes of core/back strengthening exercises.
I am healthy, fit, and strong AND NO MORE BACK PAIN.
It will take you about 3 months for the pain to go away, but you will see it decline and fade away. I can sit in a chair, play on the floor, pull weeds, pick strawberries, bike ride, life heavy objects.
Make fitness part of your life, you will feel better and can escape regular chiropractor visits and addiction to pain medication.
I could barely walk a few years ago. I couldn't jump without intense back-pain and now I can run, jump, and play in my mid 40's.
Even if you can barely move, start today. Visit your local YMCA, get a trainer, start slow, keep at it, and slowly day-after-day you will make gains and in 3 months your core will be able to take a punch from Mike Tyson and you will be strong and fit.
A strong body core is like a second set of back muscles. It supports you and holds you together. When you tighten your core/stomach it helps you back. immensely.
There are no quick fixes in life, no silver bullets, no magic pills. You have to earn the gains. No one can do it for you. You can't buy it. You can't steal it. It is something that requires routine and a little mental toughness. Do it, it will change your quality of life.
Remember this, by saying, "Oh, I don't have time to work out, exercise, or strengthen my core." what you are really saying is that, "I am choosing not to make my physical fitness and quality of life a priority." Say it outloud 3 times and see how it sounds, "I am choosing not to make this a priority, then add I would rather have back surgery and spinal fusion surgery, and be addicted to pain medicine."
I do it 3-4 time per week at 8PM. I am choosing to make my health and quality of life a priority. I don't want to be in chronic pain. I don't want to visit a quack to crack my bones. I don't want to take 6 Alleve pills per day.
As a side benefit, putting on muscles will help anyone who is pre-diabetic, and it will lower your cholesterol. Exercise has an amazing effect on the body.
Do it. Put down the DAMN COMPUTER and drive to the YMCA or GYM with a trainer NOW. Go, get off your ass. Start slow, give it 3 months and you will be a new person.
