I was (still am a tad) a fully paid up member of the dreaded sciatica club and as others have said, I think childbirth was preferable.
I lasted a few weeks before having immediate surgery or I would have jumped off a cliff. This was all during the summer and all the surgeons seemed to be away... except one. I went to see him and he seemed (dare I say the word on an 'older' people's forum?) quite elderly. Bearing in mind he was going to rummage about near my spinal chord, I had second thoughts about possible shaky hands but in the end went ahead. Bliss! Well, OK after horrible post-op period, bliss.
So, none of that helps you, Yogadatti! However, I can be of possible assistance with some exercises I was given which I still do if I feel a little of the old pain trying to rear it's head again (on the other side!).
These are both very simple and can't do you any damage: lay on the floor, legs straight out. Imagine there is a string on one foot and it is pulling your whole leg forwards. The idea is to stretch the section of spine that is causing the pain, out. You keep on and on stretching - you will think you can't go any further but you can!. Relax, then try the other leg too. The other simple exercise is to also lay on the floor. Make a triangle with your leg and the floor by lifting your knee up, pointing to the ceiling. Keeping your foot on the floor very V.E.R.Y. slowly turn your knee outwards so it meets the floor. It should take half a minute or so to do this. Then reverse the process. Do both legs. This is time consuming (well a few minutes) but I assure you that if you have real sciatic pain you'll beg to try these! I would do these several times a day without overdoing it.
In-between, I used to lay on a sofa with the affected leg up in the air, the only way I could obtain some slight (but not total) relief. Strong pain killers sent me to sleep for half an hour then it was back to normal.
When in bed, try a pillow underneath your knees - it can reduce the pressure on your spine.
Whilst in this position or any other, try to work on your pelvic floor/stomach strengthening exercises. This helps provide a girdle around your middle which supports the spine. Well, that's what my physiotherapist told me and it seems to help even now.
Wishing you the very best of luck with your sciatic journey. Hopefully, you won't have gone too far down the track and can be sorted out!
