Hi.
Thanks for your query.
Noted your history of 5 little bumps without any head or leakage of fluid in a kind of a group on the chest for 6-7 days.
You are also taking wellburtron/
bupropion 140 mg for about 6 weeks, plus, have been eating an occasional MM lollipop (40 mm/lite dosage).
Since you have been taking the above said medicines for 6 weeks, it is not likely to cause such a skin reaction after 5 weeks of usage.
Hence it may be due to some reaction to insect bite or may be just ill formed sebaceous cysts.
I would advise you the following:
Keep them under observation.
Consult your Doctor to get a proper diagnosis and treatment if any.
Please do not try anything at home as it will change the character for diagnosis to be made difficulty.
You would have posted pictures for me to do on-the-spot diagnosis.
