Does insomnia lead to body aches or vice versa?

Yes it can. We see people with widespread body aches. These are usually people with fibromyalgia. Things that can make it worse include poor exercise and /or poor sleep and/or poor control of stress and psychological issues. When sleep is improved, by correctly idenifying the cause of the poor sleep and sometimes a sleep study can help, the body aches can improve. The muscle pain needs exercise!
