<s>[INST] I popped a whitehead pimple on my chest by squeezing it. Pus came out. The next day the pus came back. So I squeezed it again. I also put peroxide and antibiotic ointment on it. The next day the area was very red, inflamed, swollen, and extremely tender to the touch. I did not squeeze anymore but the area has stayed swollen and inflamed for a week now. There is also a large hard lump there now. It has been a week and the tenderness and lump size has decreased somewhat. But the hard lump and redness is still there. Did I cause a bruise under the skin? Is it infected? Will it heal on its own in time? Should I see a Dr? Thank you. [/INST] Hi dear,From what you have described it looks like you had a pimple and when you popped it, you introduced an infection, which most likely happens when the bacteria on your skin goes under the skin. I would advise you to take oral antibiotics and topical antibiotic cream.1. Oral antibiotic preferably augmentin 1000 mg x 1 tablet x 2 times daily after food for 5 days2. Bacitracin cream x 1 application x 3 times daily for 7 days3. If there is pain for then you can take ibuprufen x 1 tablet upto 2 times daily as needed (after food)Avoid contact with water as it can delay its healing.I wish you good health and an early recovery.If you have further questions you can contact me. Best regards. </s>
