Hi..
Welcome to HEALTHCARE MAGIC..
So sorry to hear about your problem and will try me level best to resolve it to the best of my knowledge and understanding..
As per your complain painful lump forming on the jawline of your daughter that is infront of the ear seems to be due to Pre- Auricular
Lymphadenitis that is swollen pre- auricular [meaning infront the ear] lymph nodes..
Other cause for a lump infront of the ear can be due to infection in parotid
salivary gland that is a major salivary gland and also an important structure present in that location..
Yes, you should take her to the hospital and get evaluated and they can advise her to take a script of antibiotics and also do cool compresses over the swelling..
It will help her with pain and infection..
In the morning take her to Paediatrician who can do an
MRI or
x ray to confirm the exact cause for the swelling and will treat accordingly..
Hope this information helps..
Thanks and regards.
Dr.Honey Nandwani Arora.
