Hello and thank you for your time.
Case – Male 41 unidentified bacterial infection leading to GBS presenting as bilateral facial paralysis with left arm weakness. Received 3 days IV IG – drug error led to 2 days given 2 days not given over a weekend then 1 further final treatment given on the Monday. Some facial movement has been regained however now showing swelling of upper lip wich leads to my question.
Is swelling a normal part of the healing process or, is this something that requires further investigation?
Many thanks for your attention.
Regards
Mike
