my father in law just got out of the hospital yesterday. He was in for 9 days after suffering aspiration pneumonia and had a mild heart attack. He is 88 years old. He was sent home with home oxygen and has been prescibed pavix - 75mg, senokot - 8.6mg., apo furosemide - 20mg, lipitor - 40mg, aspirin and a multi-vitamin. He has just complained to me about pain in his lower left side which is his chest because at his age his chest has dropped down. What should I do?
