<s>[INST] Hi my name is Haley and I m 11 weeks and 5 days pregnant with my second child. Well about week or so ago I noticed my upper thigh by my pelvic area felt a little bruised. I didn t think much of it so I let it be. Well today I decided to actually look at it and I have a knot in this area. It s not read or hot or anything it just feels like a big knot and it hurts when I touch it. What is this? And could this hurt the baby? [/INST] Dear Haley,Your history and the description of the lesion suggest that you have caught infection at the bruising site which has caused involvement and infection of the lymph nodes that are situated in the groin (Inguinal lymph nodes). You will require an antibiotics treatment. With appropriate antibiotics the infection will be controlled and the gland will subside. If you delay the treatment, it may progress to abscess formation which requires incision and drainage in addition to the antibiotics. Please report to your Obstetrician ASAP. During pregnancy (even otherwise also), infection should never be overlooked, ignored and neglected lest the serious complications. I hope this helps you. Dr. Nishikant </s>
