You may also want to check out Dr Sean Ng from Ardmore Orthopaedic Clinic. His clinic is at Mount E. Dr Ng has helped me with a sports injury a while back and is currently treating a friend for back pains. He's really good.
I think the best move to do here is to see an orthopaedic doctor. He/she would know if your injury concerns an ortho or a neuro. I'd like to recommend to you Dr Sean Ng of Ardmore Orthopaedic Clinic, he's one of the best we got here in Singapura.
