Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain sudden sharp prick over the leg along with appearance
of two black dots adjacent to each other seems most probably be due to any insect or
bug bite..
The area is appearing swollen and raised like a bump due to the poisonous sting that causes
allergic reaction in human body leading to inflammation and swelling..
I would suggest you to take anti allergics like Levocetrizine or
benadryl and also anti inflammatory painkiller like
Ibuprofen..
You can also do cool compresses to reduce inflammation and swelling..
Apply
steroid ointment to reduce the swelling and redness..
You should also take a close look at the site and if the stinger is embedded in the skin remove it gently..
In case if still there is no resolution consult a General Physician and get evaluated..
Hope this information helps..
Thanks and regards.
