Hello everyone, I have some problem with many medical question, Could someone please help me. Thank you so much
Question 1: A 48 years old mother of 7 children is complaining of aching pains in her legs, which she reports is getting progressively worse since the birth of her last child and gaining 15 kg in weight. During her physical examination, numerous large varicose veins are observed on her legs. What is the cause of these varicose vein and are they associated with the pain she is experiencing ?
Question 2: IF a blood clot formed and blocked the coronary artery of a person what would be the first sign and symtoms that something was wrong? And would they feel any pain and if so what would be the cause of this pain. ( FOR MY OPINION, I think the first sign of this is a heart attack but Im not sure about it )
Question 3: Early in the history of medicine, surgeon know the immune function of the thymus was and the gland was sometimes removed !. what complication would u predict a child might display after the removal of this structure ? Would the child be more prone to viral or bacteria infection ?
Thank you for any of your comment or reply.

NO, I DONT THINK THAT I HAVE HAD ONE!!!!! I just have an unusual intrest in health care ( i plan on being a nurse). I know that sometimes, Myocardial Infarctions (heart attacks) can happen without any symptoms, but in my CPR class, the symtoms sounded like they would take a toll on the body, pain-wise. so, if u do have a heart attack in ur sleep, wouldnt u wake up when u started to loose blood and have chest pressure. like in sleep apnea, when ur brain starts loosing oxygen, u wake up. so, is it the same with heart attacks? just curious
