I am breastfeeding my 4 months baby birth weight is 4.2 kg delivery was normal vaginal delivery. I was very normal and healthy. one day suddenly started raining, was raining continuously for 2 days (31st august and 1st september) it was chill weather. I had headache whole day on 1st september and also whole body pain but no fever or cold. The next day I had a small mass in groin (posterior) and had menses like cramps and the next day I had spotting. Now (4th september) I have spotting and menses like cramps and the mass in groin size is increased. My question is should I consult a doctor? Is this a serious health issue? Or it will subside on its own.
