One first-time mother shared a photo of herself and her baby without knowing she would receive warnings that later saved her from a serious problem.

Only eight weeks after her daughter's birth, "Married At First Sight" celebrity, Zoe Hendrix, shared a photo on her Instagram page of her baby, Harper-Rose, laying on top of her.

Comments from followers warned Hendrix about something she thought was only the flu.

She shared:

"SICK AS a flea bitten dog in the backstreets of Bali. Except I'm not in Bali, I'm in bed with a temp of 39, sore throat, body aches and an 8 week old. I salute all you mums/dads with chronic and serious illness who get up everyday and push through the pain and take care of your kids."

It wasn't the flu

Several of her followers realized she may have contracted something more serious than the flu.

Heather Snapper commented:

"Sounds like mastitis. I got it about 7 times while BF, so I used to ask the Dr. for the prescription to have the antibiotics on hand and ready to take at the first sign of infection, to lessen the severity."

Hendrix went to the doctor and found out she had mastitis infection

Hendrix thanked her followers when she posted a week later, saying she was finally starting to feel better with help from antibiotics and her mother-in-law.

What is mastitis and how is it treated?

Mastitis can be painful, and its symptoms are often confused with the flu, especially in new mothers, according to WebMD. This condition should be treated with antibiotics in order to avoid more serious complications.

This infection is caused by bacteria that enters the breast through a cracked or sore nipple and is more likely to happen if:

• You've had mastitis before

• You skip or delay breastfeeding or pumping milk

• Your nipples are dry or irritated (which can result from poor placement or poor latching while breastfeeding)

• You have anemia

This infection usually begins with breast pain, but body aches and fever can be early signs and trick you into thinking it's a common illness like the flu.

You can continue breastfeeding

Mastitis doesn't stop you from being able to breastfeed or pump your milk, according to WebMD. If you suspect you have an infection, visit your doctor to receive proper treatment and antibiotics so you can be healthy for yourself and for your baby.
