Afraid to be active

I have a herniated disc (L5-S1) that turned into sciatica last week. I couldn’t walk, and had to take the week off work. This is the third major flare up due to my herniated disc. I believe it was caused by doing some stretches. This has made me a bit afraid to do physical activities. I like going to the gym and playing golf, but I’m afraid I’ll do something to irritate it. I have an appointment with a surgeon next week, as I may need surgery… but does anyone else feel the same?
