Lantus and cough

I have been on Lantus 40 units 1x per day and I too have had excruciating back pain that runs from my neck down to my waist and in both shoulders. Also I have a cough too which started with a cold but the cold went away and the cough did not. I also have woke up in the middle of the night sweating and shivering never had this before either. When I asked my doctor about this he said oh sounds like fibromyalgia WTF?? Never had this pain before or any of these other symptoms and it starts right after starting a new med(Lantus) I might not be an md but it doesn't take a rocket scientist to figure out that it is the Lantus causing this . Why don't doctors want to admit that every drug has some side effects and I am starting to thing insulin has the most.

restless legs at night, severe leg swelling especially in the evenings, itchy rash on legs, possible eczema ( I have never ever experienced until Lantus), insomnia...I can't string more than 3 hours of sleep together at one time, wake up with cold sweats and confusion, really bizarre dreams, weight gain (rapid), severe cough, terrible back pain....sometimes standing for more than 10 minutes kills me.....Is it just me or does Lantus smell horrible?
