Ay mama, that sounds stressful talaga! Since the bukol hasn't gone away kahit after hot compress and it's been a while na, I'd really suggest getting a second opinion from another pedia, sometimes these lumps need a proper check-up or ultrasound to know what's going on, especially if it's been there for a bit na. One of my mum friends had something similar with her baby and it turned out to be nothing serious, pero she felt better after getting it properly assessed kasi peace of mind talaga, hindi lang based on home remedies.
