Hi...
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns...
As per your complain it seems that you have bitten by a poisonous insect leading to a severe localized
allergic reaction and it is the cause swelling of the fingers..
You should take anti allergic medication like levocetrizine or
benadryl, take anti-inflammatory medication like
Ibuprofen.
Apply a steroid ointment over the swollen area to reduce inflammation, you can also apply
calamine lotion to reduce irritation and soothe the skin..
Do cold compresses over the swollen area..
In case if there is no improvement or the swelling exaggerates consult a general physician and he can advise you injectable anti-allergics and
steroids for faster relief from the inflammation and swelling..
Hope this information helps..
Thanks and regards.
