Thanks for using Health Care Magic
I would be pleased to answer your question .
What you can feel under the skin is the collagen
and dermal swelling ( edema ) . This will take some time to go . It is recommended that you should allow the bumps under the skin to remain for a while as the collagen re modelling is underway . You should not interfere with it as it will alter the results you get for the scar treatment . You can apply Tea tree oil or even some apply some ice on the area daily for 2 weeks .
Thanks and Take care
