Sciatica

Played football 2 weeks ago, felt a sharp pain in my back... Stupidly stayed on and hobbled through the last 10 mins. Got home that night, and I was in agony. Took 2 days off work... The pain went from a 9/10 to a 6/10... So I went back to work. My job requires me to sit down for long periods at a time... After 4 days back at work, I was in terrible pain.. I now have pain in my right hip, down my leg and in to my ankle. Doc gave me Neproxem (sp), which helps the back pain, but not the pain in hip/leg/ankle.
Do I man up and wait it out?
Osteopath?
Chiropractor?

Thanks in advance
