I have been on this for only 5 days- I also have the achy feeling...

I don't think you're alone feeling these symptoms. After reading the side effects other people on this website are having, I felt more certain to discontinue taking the drug. The achy feelings in your muscle may attribute to this drug. I have only been taking it for a month and I am experiencing aches and cramping sensation on my left leg/calf. The discomfort keeps me up at night and I feel tired in the morning so I am a little irritable. Other symptoms I have never had before are hot flashes, stomach bloating and gas, and weight gain (including inches).

I went to the doctor and found out that the achy muscle symptoms were due to lack of calcium, magnesium, and potassium. The doctore recommended that I take vitamins with large doses of these minerals in them. He also recommended for me to buy food that has potassium in it and to incorporate it more regularly in my diet. So, the muscle aches and pain are a side effect of Lisinopril.

Hope this helps!
