unexplained fever / acne

Ok, here is my story: 3 years ago I was badly stabbed and nearly killed. I went through a life saving surgery (which took 8 hours). This included open chest/abdomen surgery and I was transfused 16 units of blood. It took me a lot of time to recover mainly because of my collapsed lung. Initially I was on morphine for a week and then I was on all sorts of drugs and antibiotics for the next few months. About 3 years passed and I was doing just fine when suddenly I started having a mild fever which worsened during night time. I've had this fever daily, for the past 7 months and doctors couldn't find out what is causing it. I did a lot of blood tests and everything came out negative. Can anybody suggest any alternative treatment because I’m so sick of being sick? Now my second problem is my skin. I've had perfect skin all my life and suddenly I started getting what looks like huge blemishes on my forehead. They develop slowly, in groups, close to each other and never break out... It’s like they are deep under my skin. They also tend to get very big and painful when I touch them. It takes a lot of time for them to heal. I've also noticed they only develop during winter time and that I get few spots on my back as well, at the same time. My skin also gets very, very dry during winter. I went through antibiotics treatment (amoxicillin) and my forehead cleared out for months and then it all started again. No medicine so far has worked for my fever nor my skin problems so I am really keen on trying homeopathy… any suggestions are welcomed. Thank you
