What Causes Chest Pain Despite Taking Tylenol After An Injury?

I fell forward five days ago, hitting my chest. Upper chest felt o.k, but numb all afternoon. Did have slight pain below left breast during the afternoon. Took Tylenol (on blood thinner) for pain. Slept very little first night. Four days later, am in terrible pain, little sleep and can hardly get out of the bed in the mornings. Pain covers entire chest, left to right, until walking around. Breathing is beginning to be painful when talking on telephone. After 1 or 2 more days, plan to see my doctor. Do you think healing can be done at home? (83 years old )
