A marble-sized painless lump that has sat quietly for four years, moves freely under the skin and is just below the surface is a benign scalp cyst or a lipoma - not a tumour. No cream, tablet or oil dissolves these. The only permanent cure is a small excision under local anaesthesia, a day-care procedure done in 20-30 minutes.
Next Steps
Since it disturbs your sleep and haircuts, get it removed rather than just watched. An ultrasound of the swelling will confirm cyst versus lipoma, and then a minor excision by a surgeon finishes it in one sitting. Never squeeze or prick it - that only invites infection. Also get a
TSH done so your eltroxin dose stays correct. Consult me on Practo with the ultrasound report and I will guide you through the removal and pre-procedure check-up.
