hi well come to hcm.
If she has no restriction as far as daily activity other than pain you can very well wait.
Give her some analgesic
with anti inflammatory action drug like ibuprofen
provided she is not allergic to it.Continue applying ice.Itching may be due to allerrgy
to drug you have taken can give some antiallergic like cetrizineIf no response ie if
bumps donot go down consult your Doctor.Thanks
