Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain swelling and
facial rash after taking tobacco seems to be due to
allergic reaction only and it seems to be severe as it is happening even after 2 weeks..
You should continue another 3 days course of anti allergics like
Benadryl..
You can apply cooled
aloevera gel over the face to reduce inflammation and peeling..
You should do cool compresses over face and lips..
Avoid application of any chemical cosmetic over face..
You should drink plenty of water..
In case if there is no improvement in 3 to 4 days consult an Allergist and get evaluated and a thorough clinical evaluation and investigations like Allergic tests can help in diagnosis and treatment can be planned accordingly..
Hope this information helps..
Thanks and regards.
