Can anyone help with a few ailments I am having with my legs and backside of head?

I am 28 years of age. I am a male short with athletic build. I am having terrible pain in my legs. They throb and pulsate. It has been determined not to be restless leg syndrome. I am single and don't go out much. I have 3 dogs so I workout a lot feeding, loving and trying not to wear myself out too much. They are Jack Russel Terrier so they wear me out regardless. Someone please help me and I will tell you about the pains in the backside of my head. For instance my whole head never hurts it is just the backside. There is more to my problem so I hope someone will help me by e-mailing me as soon as possible.Oh one more thing the doctors put me on LYRICA if that helps you help me. The medicine makes my lower back hurt so bad and nothing will help with the pain. Like I said please respond and we can go from there.Thank you.
