(Undated) -- Household chores are a pain in more ways than one. Occupational therapist Mike Milicia says the most common complaint is people hurting their back while mopping or sweeping. Milicia says to always step in the direction you're vacuuming to avoid reaching and bending. If your back hurts while doing the dishes, open up the cupboards below the sink. It'll let you get closer and might alleviate the back pain.
