Pulled ligaments symptoms and conditions

Ive been taking lotrel for nearly two months now. I have had bad elbow, both of them, aching in the joints and right shoulder stiffness. I cant even take my right arm behind me to reach for anything out of the way without a severe pain in my shoulder. It is like being fractured or coming out of joint.
I explained this to my doctor and he thinks I have pulled ligaments or something. My elbows get so swollen in the morning that I cannot bend my arm or pic something up. Believe me, I am not older or have any physical problems in the past.
I am not sure what to do and I know I need to be on some sort of blood pressure medicine. Ive tried two or three others and they have their own set of side affects. Its sorta like, pic my poison so to speak!!
