Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that the symptoms of hives and rashes around the mouth along with swelling of the lips seems to be due to
allergic reaction only and the most common cause of it seems to be due to some food or medication, skin cosmetics etc..
Increase in blood pressure also seems to be due to
anxiety and the symptoms that she is facing..
I would suggest you to consult an Allergist and get evaluated and a thorough clinical evaluation and investigations like allergic tests like
Patch test, RAST test, food challenge test etc can help in diagnosis and treatment can be done accordingly..
The tests will help in ruling out the exact cause of the allergen and once you know the cause of the allergic reaction you can avid exposure to it to prevent allergy attack..
She should continue taking
benadryl as advised by the physician and can do cool compresses over the lips and the effected area..
Apply
calamine lotion..
Wash your face with cold water..
Take a nutritious diet and sufficient rest..
Hope this information helps..
Thanks and regards.
