Hi, I have sciatica as well on my right leg. The doctor didn't prescribe strong medication because I am pregnant, just paracetamol. Before, I was advise to see the physio but I was pregnant on my second child so I was just taught light exercises. Unfortunately, I didn't do any exercise due to being busy on my children and at work. But the doctors says that once you have sciatica pain, you need to remain physically active. But in my case, at the end of the day, my back aches a lot especially when I am in bed already or just sitting. It will take some time for me to stand up due to the pain I am experiencing. There are suitable exercise for every pain, you might as well see your GP so that he may refer you to a physiotherapist. The last thing that you wouldn't want to happen, most of us is surgery. But they said in every surgery there is always a risk. So the decision is yours. Just ask advice to the health expert who knows more about your condition. I hope my opinion helps you. look after yourself always.
