Hello dear,
The symptoms as mentioned in your post can be attributed to
Folliculitis.
It occurs due to infection/inflammation of hair follicles.
As it's producing yellowish green mucus (pus) it indicates that the lump has got infected.
So, kindly consult your Physician & get it drained under strict aseptic precaution with antibiotic cover.
One more thing...please avoid squeezing the bump, as it will aggravate it further.
Further management will include:
1. Application of topical antiseptic ointment.
2. Topical antibiotics such as
neomycin ointment
3.
Analgesic & anti-inflammatory agents for symptomatic relief.
4. Multivitamins & zinc to assist in healing process.
There is no need to worry, you will be fine.
Take care.
