Hello and welcome!!
You've come to the right place! We've got some great members on these forums, and I hope they add their awesome and insightful answers to this as well. I'll try to give you the 'no B.S., no ego answer' with a few "games" to try that will dramatically simplicity the healing process for you.
Sciatica sounds to me like some sort of 'crystallized' energy that is 'trapped' or 'blocked' in that particular spot. Instead of shrinking away from the pain, turn it into your object of meditation. How do we do this?
Well, let's go back to the 'basics' and go with "what are you made of?" simplistically speaking, you might respond with 'well, energy'. What then is the difference between mind, body, star systems, the earth, water, wind, etc, etc...they are all made of energy too. Even ideas and visualizations are made of energy. Energy contains instructions or information with it, it's not just 'doing something' the info contained within--IS it's behavior.
So how can we make sense out of this, and use it for practical purposes that will aid us in our daily life? First let's start off with a simple energy sensing exercise that I think will help...
Put your hands a few centimeters apart, and slightly open fingers, palms facing each-other... Relax and just 'visualize' or imagine that 'something' is jumping between your hands and connects an energy circuit. You could visualize 'light' or electricity like 'lightning' is smoothly connecting your hands together. You should feel *something* --this isn't a race, just take your time and give it a few minutes if you don't feel something right away that's okay too.
A subtle 'energy' feeling will come up, this is 'your field' or aura, it is quasi-electromagnetic in it's nature. Coming off of your fingers and hands, it should feel pretty smooth for the most part. You'll also notice, that your mind, is able to 'flow' between and through this energy and get a sense for it...
Now try the same thing for your shoulders, flow your mind into and through the area the feels uncomfortable (or dense) in your energy, try to "feel" the uncomfortableness--notice you've set up mental labels for it, but it also has information of it's own. (the original information that is the 'stuckness' of the pain or problem, AND the energy you've labeled it as)
Just notice the 'energy-labeled-as-pain', don't try and "get rid of it" --we already know that won't work, at least with lasting results. So, what else can we do?
Let's just "hang out with it" 'as energy'...
Simply 'hang out' with the 'energy-labeled-as-pain' by being in a state of emptiness (by just flowing or shining your mind through it's energy is usually more than enough)...
This (gently) forces the energy to change state. It has to do *something* but because we are not 'trying to change it' and are just 'hanging out with it' --the mind, starts "using UP" (almost as fuel) the energy you are looking at.
Why does this work so wonderfully well? Because you are thinking "from" the pain, and not "into" it.
