Hello,
From the pictures that you have posted it looks much better and on the path to resolution. There is no harm in doing occasional hot compresses. Also you may use Ocupol D or Neosporin H ointment locally over the bump and massage it thoroughly with clean washed hands at night before sleeping.
Continue this for a couple of weeks and observe. Should resolve mostly by then.
Health Tips
Don't use the ointment for more than 3 weeks on your own without a follow up check up as it contains a mild steroid.
