Sciatic nerve pain after exercising

I would suggest a physiotherapist or a massage therapist. I've had that problem on and off for a few years. They gave me a couple of exercises that work really well. My hips are not well balanced (sorry, can't find the right wording in English...) so it pinches my sciatic nerve. But my massage therapist and my physiotherapist are a great help when it comes back.
Good luck!

I developed a case of sciatica about a month after I started on my weight loss program and exercise. It was SO difficult. For several weeks, I had pain day and night. I tried stretching exercises too...didn't help me. I went to the Dr. and he prescribed muscle relaxers which only put me to sleep. He told me I could have it for a short time or the rest of my life. It took about a month but it finally went away and I started to exercise again and was fine. I have had no recurrence.

I guess what I am saying is that I had to stop exercising until I was better. I continued my healthy eating and I still lost weight, albeit more slowly. Maybe Yoga will help you. Just don't push yourself....take things slowly. Give yourself time to lose a little of the weight and I bet you will be able to increase your exercise.

I occasionally get sciatic pain due to tightness in my piriformis muscles. A yoga move called pigeon pose is one of the only things that help me when it flares up: http://yoganesh.net/video-easy-proper-pigeon-a-piriformis-workout-for-the-rest-of-us/

I also noticed that if I don't stretch that muscle after exercising, then the next day I can count on sciatic pain.

This type of stretching helps me too. I think a lot of sciatic pain is caused by the piriformis muscle being too tight, as it naturally is for most people. As long as I stretch after each workout, I don't have sciatic pain. One move I do is lay on my back, cross one leg over the other in a "formal" sitting pose, and pull both knees towards me. Then cross the other leg over and repeat.
