OK here you go.....
If you can sit as you men do with the ankle of your bad leg resting on the knee of your good leg so your bad leg is relaxed. If you can't do this get Mrs Oi to follow the rest of the instructions.
Using some oil/cream trace a line in the channel between your shin bone and your calf muscle on the INSIDE of the bone from your ankle bone to your knee. now, using your thumb using a wave motion work your way up the inside of your shin bone. You will find 'dents', these are 'lack of energy' points and could be very sore. Once you get up to your knee use your other thumb to repeat the wave pattern down from your knee to your ankle. some of those 'no energy' spots might not be there on your down massage. Tip...keep the edge of your thumb against your shin bone. You keep repeating this up and down massage using alternative thumbs until the 'sore spots' don't feel too sore. Repeat the whole process 2-3 more times a day.
Now if I remember correctly, you also use essential oils yes? If you do add some juniper oil to the carrier/cream. You should know how to work out the dosage. Juniper oil removes 'blockages'.
Those 'sore spots' should start easing off quite quickly. Think 'energy flow' here. As the energy begins to flow so those dents and divots will 'fill up' and the chanel will feel a lot smoother.
hope my explanation is ok and it helps.

PS...there are a couple of other more manipulation type things and tsubo spots you could try, but as one of them involves your sitting bone...you can't do them yourself! lol! You should be able to get it sorted with the above. As is the rule with sciatica...the longer it is 'bruised' the longer it takes to heal...hopefully we have caught it soon enough. I have seen someone get up after being wheelchair bound just short of a week of starting this treatment
