Sore testicles symptoms and conditions

I am 53 year old male and began taking Diovan 160 dose in JULY 2002. I have dizziness, nausea, fatigue, some weight gain but changed diet and lost the extra 20 lbs. Of course, I realize the fatigue is due to the insomnia. I can be feeling OK and all of a sudden feel nausea, chills, sweats and have to lay down sometimes it last for days; other times just a few hours. I have a thumping in my throat with every heartbeat, which causes a headache. Am always complaining of lower back and joint pain. My eyesight is ever changing for the worst, has is my impotence. Open to natural ways to lower BP.
