That is so, move the saddle closer to the bars so some of your weight is shifted a little more on the bars.
I had a very bad sciatic nerve episode from bicycles many years back, but not riding them, I imported and re exported bicycles into Singapore also had five retail shops on the island, at weekends I would help out in one or other of the shops, customers would always want to try a bike which was usually the one at the back behind the ones at the front, so lots of reaching over and lifting whilst bent over, not good!!
My doctor and chiropractor wanted to refer me to surgeon, I was not keen and borrowed a two channel tens, the first day I used it was the first time I was able to sleep without pain.
If used correctly you put one pad on the damaged area and one pad on to an accupoint, the pad on the damaged area helps regenerates tissue and promotes healing, the pad on the accupoint blocks the pain receptors.
I have a couple of tens machines my original four channel from China and a more modern one from Lazada.
