Half side body pain. What i have to do.

Good morning I'm Ravi Tholiya 1st year mbbs student. Sir/mam I feel burning and shooting pain on the side of my neck and shoulder and my whole hand . It is like sometimes on the right side and sometimes on the left side . Actually I have gone through Cervical spine MRI but report saying that I have mild posterior bulge on c6 c7 disc and loss of cervical lordosis. The doctor said that it's normal it's mild no problem They sent me to the physiotherapy department for neck exercises. I have gone through physiotherapy 10 days but it's not gone . And now the pain is also gone into my lower back and legs. Like when I feel pain it's like totally half side body pain. Also joint are hurting (all joints of upper limb ) Now what I have to do.
