Hello and thanks for writing in at HCM
I read your mail in detail. The swelling in your leg may be due to insect bite or allergy
to the grass present in the yard. I don't know whether you have fever
or not, local area temperature raised or not, severity of pain. You have to immediately consult your physician and get a course of antibiotic and anti-inflammatory, anti allergic if itching is present or advised by your doctor. This may lead to formation of abscess
and may need I and D, if you delay it. Consult your doctor ASAP.
