I have continuous back pain. During my pregnancy i have not taken calcium and iron supplements due to excessive vomitting issue. My child is now 2yrs old and still i am breast feeding him. I had c section. I have continuous back pain. As i do house hold chores the pain starts increasing. And i get exhausted too early. Within very short time my energy level goes very down. I feel weakness in my legs and body and back pain increases. Before pregnancy also my energy level was not that good. Please guide me
