I think i have a fecal impaction. if i eat a lot of prunes/prune juice will that clear it all out? without me having to go to the doctors.

Constipation: Fecal impaction is commonly caused by lack of bulk forming stool (low fiber for example). There are several OTC medications available for treatment of constipation, but you should first try simpler methods such as high fiber food. Drink plenty of water as dry stool leads to impaction too. Change your diet to include more fruit and vegetables and exercise regularly which helps as well.
