Hi I.,
Are you still taking your prenatal vitamin? If so, is it absorbable? Are you nursing?
Childbirth can be exhausting on a body and it needs to be strengthened. The illnesses come and go and you can rebound back to health but the antibiotics will actually break down your immune system so you'll get sick again and the doctor will give you more antibiotics. The body is meant to fight off infections by itself. Antibiotics were created for life threatening illnesses. We live in a "fix it now" society so doctors don't allow the body to even try to heal itself.
If you're not on an absorbable multivitamin, find one. I take one that is guaranteed to absorb and I can feel it. You also need eight hours sleep a night. If you're not getting it ask hubby to help out. Exercise is great. Do as much as you can, but try not to overdo.
I detoxed my home and I don't get sick anymore. I also have a chiropractor as my primary physician. Chiropractors understand the immune system and how it is supposed to function. Keep things like Beta Glucan and Elderberry syrup in the house so when you feel something coming on you can help your body fight it. It's much easier to prevent something than to cure it.
If you do decide to do the surgery, there are things that you can do before hand that will help the healing process. I can point you in the right direction if you like.
God bless,
M.
