Pain in fingers, hands , legs. Help me.

Greetings doctors, From last few weeks i'm having pain in my fingers , hands , legs and  both sides lower back side where i wear my jeans. And also having headaches at one side of my head.. usually the pain is not that painful.. and i don't even come to know about my pain when i'm busy in some physical activity but when i sit for my studies or i use mobile phone i feel some pain in my body for few secs and later it goes away. I'm overweight right now and trying my best to reduce my weight. My hb is high and it is around 17.50 (reports attached) and i'm very tensed about condition because i've never felt these things ever before. And in addition because of google and after reading about CKD and Lupus , i'm getting more worried. For background history i do get hives once a year and get cold easily. Please help me. Thanks in advance for your kind help doctor.
