Read the following context and choose the best option to answer the question.
Context: After all this time I expected there to be major damage , and that I might need surgery to fix it - but thankfully , that 's not the case at all . Apparently ( once the jargon on the report was translated into English ) , I have two bulging discs that are in danger of slipping , and one bulging disc ( the first one I injured ) which is already slipping . The recommended treatment is strengthening muscles in the area through light exercise ( walking , aquarobics , pilates , etc ) , possibly with a little remedial massage thrown in for good measure , as well as losing a little weight and improving my posture . If I can do these things ( and do them sensibly ) , then eventually the problem should correct itself . Yay .
