Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that due to
bug bite there has been
allergic reaction to the sting of the organism leading to swelling, redness and bruising can be due to rupture to any small blood vessels..
There is also a possibility that there is infection at the site of bite leading to increased swelling and worsening of the lesion..
I would suggest you to consult an Allergist or General Physician and get evaluated..
In case of allergic reaction he can advise you to take anti-allergics like Allegra and apply
Steroid ointment over the swelling and do cool compresses..
In case of infection you can be advised to apply a combination of antibiotics and steroid ointment over the lesion..
A course of
Oral antibiotics can also be advised..
If the lump is filled with pus
Incision and Drainage can be done for faster healing..
Hope this information helps..
Thanks and regards.
