<s>[INST] Hi :) I ve been having painful hard lumps (seems like blood-filled) under my armpits and in the groin area. I pierced/popped one in the groin area today (I couldn t see it very well, and I thought it was an ingrown hair or pimple). I m a 20 year old female, 5 6 tall, 210 lbs. I currently take Vyvanse (60 mg), Cymbalta (90 mg), Lamictal, (100 mg) and the birth control pill Beyaz. I m allergic to cats as well as seasonal allergies. My last period was about 3 weeks ago. I don t drink or smoke. I am sexually active, but I use condoms every time, and I don t have any STI s. [/INST] Hello! Thank you for the query.These lumps are most likely caused by shaving mentioned areas. Especially if the razors used for shaving are non-sterile. This may cause hair follicle inflammation and lead to abscess formation. If you use any antiperspirant in these areas, this might be also a reaction for it. I suggest you to consult dermatologist with this issue. Please also try to use sterile razors. Hope this will help. Regards. </s>
