Have Pus Filled Lump Below Hairline On Back Of Neck. Sore To Touch. How To Remove This?
Thank you for your query.
1. The most likely cause for such a lump to appear overnight will be an enlarged lymph node due to a scalp infection.
2. Get it examined by a local physician (as the physical appearance will help diagnose it better) and get a USG (Ultrasound) of the Neck. If there is still some doubt, an FNAC (Fine Needle Aspiration Cytology) will settle the issue. There are other possible lumps such as cysts and lipomas.
3. Posterior triangle lymph nodes are not considered XXXXXXX Get your scalp examined by a Skin Specialist.
4. Your physician may start medication for a few days and then depending upon the response, plan further investigation and treatment.
I hope that I have answered your queries. If you have any further questions, I will be available to answer them.
Regards.
