Can Physiotherapy Treat Bulged Disc?

i have the problem of bulging disc in L 4/5. when i consulted an orthopedic doctor he asked me to do a surgery. but i don't like that option. then i went to a rheumatologist and he referred me to a doctor who does physiotherapy. this is the 3rd day of my therapy and i still have no clear improvement. what i want to know is whether i would be completely cured with physiotherapy. and will i be able to have a normal life. because after this incident i stopped doing regular exercises which i did to loose weight(went to a gym). now i have put on much weight and i want this disc bulging to be cure just to started my exercises back and give away the pain.
thank you. it would be a great help if you can answer this. thank you soo much.
