<s>[INST] im 23 weeks pregnant, i dont know if this has anything to do with it, but last week i noticed a small bump on my inner right thigh, its hard and it hurts, this week it has only gotten bigger. i'm afraid it might be some serious but dont know what to do can you please help? [/INST] Welcome to health care magic. 1.There are tow possibility according to your history. First is lymph nodal enlargement which is seen in localised or systemic infection / inflammation.2.Second is vascular cause which can be suspected in pregnancy like venous insufficiency causing bulges.3.Finally localised infective aetiology with collection of pus - hair follicular infection.4.It need to get examined and a ultrasound scan will help to know the nature of the lump and its source and extensions.5.So get an appointment and get treated. Good luck.Hope i have answered your query.Any thing to ask do not hesitate Thank you. </s>
