Hi..
Welcome to Healthcare Magic.
I have gone through your query and can understand your health concerns..
As per your complain it seems that you had an
allergic reaction to something that has caused you sudden onset of the red spots.
It could be a insect or
bug bite,any food product that you took before sleep,any new lip cosmetic product etc leading to the following symptoms..
You need not to worry as it will subside soon..
You should take Allegra 6O mg twice a day for relief from allergic symptoms..
In case if the itching or pain occurs you can apply a
steroid based ointment over it..
Do cold packs over the spots..
Slowly the symptoms will subside..
In case if there is any systemic symptoms like
dizziness,
vomiting, rashes in other parts of body, hives etc you should immediately consult an emergency room..
Hope this information helps..
