<s>[INST] hi i am 17 years old. i just discovered a bump on my elbow. upon accidentally bursting it, i saw water coming out of it. 2 days later i found another one on my chin which also released water as soon it burst. it then dries and forms a bump with a scab on it. it wasn't like a pimple though. it secreted some clear liquid. please advice. [/INST] Hi,Dear,Good evening.Thanks for your query to Health Care Magic.I studied your query in-depth. In my opinion the bump at 2 sites-is-Molluscum Contagiousum-as-the elbow lesion spread to chin , and as it affects young adults also./ or could be-Pimples -common at your age.Treatment-a-Molluscum-Contagiosum-as it -Being Viral is-self limiting and could be treated by -Steroids/antihistaminics with supportive vitamins and lot of liquids.b-Pimples -need Antibiotics / NSAIDs/ and  hygine of the skin at site for to avoid spread.Hope this would clarify the worry you had.Would love to Wellcome your queries to HCM. </s>
