Im Having Problems With Both Of My Knees, Back...bulging Disc

Im having problems with both of my knees, back...bulging disc and loose cartilage in my right shoulder...I'm right-handed and have been getting injections for pain in my right shoulder. I'm unemployed right now and going to various doctors Re: my problems was thinking about applying for SSI via Social Security. Do you think I could possibly get this benefit for now?
