Hello to you all,
I am Marc from France and my job, apart from teaching Tai Ji and Qi Gong, is healing. My speciality concerns the spine and all the troubles that arouses from vertebral disorders.
The sciatic pain, as mentionned by the two first messages, can have different origins. In fact, the so called sciatic nerve shares at least three nerve roots emerging from L 2 to L 4 and sometimes from L 5 also. From these roots, the thre, four or five nerves meet together to form a "common trunk" before they split again to give birth to different leg nerves as the sciatic nerve, the crural nerve etc. If any of these nerve roots is pinched because of a misplaced vertebra, it crates a pain that expersses itself somewhere in the leg, in fonction of the nerve origin.
Know, In the first message of the list, the pain seems to take place in the waist area and the upper part of the tigh. This means, that the problem takes place at the junction between L2 and L3. This is quite logical when you think that the original pain has started while working on "kicks". If you observe the spine mouvements during a kick, you will probably discover that the spine, to maintain the upper part of the body strait and authorize the lower part to be raised for the kick, then this double effort makes the spine "fold in the area located in the"lowest part of the mid spine", just where are located the L2 et L3 vertebras.
In the second case discribed in the second message, the trouble also takes its origin in the sciatic nerve, but this time, it probably starts lower on the spine, and between L3 and L4. The pain, is identic in the two cases, but this time, the pain apears a little bit lower on the leg.
For information, if the nerve of L4 L5 is pinched, the pain goes lower on the outside of the leg and to the ankle. When it is the nerve emerging from between L5 and S1 (first sacral vertebra) then the pain also goes down to the ankle, but this time, it also runs around the ankle to the inside of the leg.
Knowing this, you can easely understand the treatment you have to apply to your pain: you have to have a kiropractor or an osteopath replace your vertebras. Then, and only then, you should practice the proper Qi Gong exercises, and Tai Ji, to accelerate the heailing process by bringing more blood and energy to flow in the area.
I hope these few lines will help find the way of a better condition,
