I'm On My Fourth Round Of Antibiotics, The Last Two

I'm on my fourth round of antibiotics, the last two included cortisone treatment, in just over two months. My sinuses are stuffy and bloody and I have sharp ear aches every few hours. Sore throat sometimes and swollen glands. Right now my skin on my upper body is extremely sore to touch, even laying in bed hurts. Also putting on weight suddenly. Help please!
