Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can very well understand your health concern..
Multiple sore bumps that have arrived over your lip within an hour can be due to
Allergic reaction to some food item or anything else that have come to contact of your lip leading to reactionary bumps as a result of inflammation..
You need not to worry and can take Allegra or
Benadryl that are anti allergics..
You can apply
steroid ointment over the sores for relief..
Doing cold packs can also help..
You can apply Lignocaine gel over the sores for relief..
In case of pain OTC painkiller like
ibuprofen can be taken..
Do not touch the sores with tongue or teeth..
In case if the sores does not improve in next 2 to 3 days you need to
consult a dermatologist and get evaluated for viral infection (Herpes), or bacterial infection if you shared any lip product like chapstick or lipstick with anyone else..
Hope this information helps..
Thanks and regards.
Dr.Honey Nandwani Arora..
