What causes soreness and swelling under armpit during pregnancy?
Patient: I am currently 28 weeks pregnant and I have soreness and swelling under my right armpit. My obgyn examined me about 2 months ago and said that she didn t feel anything abnormal and that this was normal during pregnancy. Should I still be worried or get a second opinion? Doctor: Hallow Dear,During pregnancy, there is generalized engorgement of the breasts as a whole. This is due to the hormonal changes in the body. Though the breast is seen on the front side of the chest wall, it has got a tail which extends up to the armpit. This is known as The Axillary Tail of the Breast.  As the breasts get engorged, depending up on the degree of engorgement, this Axillary tail also gets engorged. So what you are feeling the soreness and swelling under the armpit is nothing but the part of breast engorgement involving the Axillary tail of the breasts. I do not feel you need any second opinion. In fact I have given you the second opinion with physiological and anatomical explanation. :)I hope this takes away all your worries.
