Cartilidge symptoms and conditions

I just turned 60 and thought all my aches and pains and cramps were due to age, but having read these posts, I believe it is the Januvia that is causing my problems.I am a type II diabetic. After taking Januvia for less than a month, I have been having trouble sleeping more than 4 hours per night. The back of my neck is stiff and hurting. Both my hands and in particular, my fingers are numb and tingling. I'm experiencing cramps in both legs and stiffness all over. I've had to force myself to stand up and walk. I have severe heartburn (something I've never suffered with). I, too, have absolutely no sexual desire.About two weeks ago, a lump about the size of a dime has formed on the cartilage on the front of my neck, just below my chin. My doctor says, "We'll just watch it." I just feel rotten! I am stopping this medicine today. I hope these side effects have not done any permanent damage to me. I'm sick of these doctor's using their patients as test subjects for new drugs! I'm definitely changing my internist because this is one of many instances where the drugs I have been prescribed have caused me extremely miserable side effects. Where in the world is a doctor that believes in improving his patient's health or curing the illness rather than "PRACTICING" Medicine and pushing drugs!

I am taking Levaquin now, but after reading all of this I plan on not finishing the 3 pills I have left. My head is numb and feeling so weird. I have a constant headache which I hardly ever have and I feel dizzy and really out of it. My stomach is sick and nauseated. Feeling almost depressed which I don't know why. I just don't feel right. My shoulders feel heavy and tingly and I feel more sick now than when I started taking it 7-8 days ago.
