Unhappy Client

I took my son to the Dr on 01 Mar 2015, he was diagnosed with lung cancer. He didn't sleep again the night after I took him to the Dr. He was sick with different simtoms that he had previous day/night. I rushed him to the nearest clinic in the morning. when my husband came back from work, we took him to the Dr for him to tell us if the sickness he has now might be caused by the meds he gave me so that we can stop giving him. & for him to change or amend my sick note for work. The Dr refused to talk to us & he told his receptionist to talk to us.<br> <br> He is unprofessional, & the receptionist was talking to us in the reception & other patients were listening to us. <br> <br> I'm worried that my son (5 months old) might be given wrong medication. I wonder if his medical certificate is LEGIT? ???
