Hi,
Thank you for posting your query.
First of all, I would like to reassure you that the itchy rash and skin lesions in the lumbar region are not related to the lumbar canal stenosis. They are two separate problems.
The
skin rash needs to be evaluated by a
dermatologist.
The most likely cause could be
urticaria, and may be related to an
allergy.
Use of antihistaminic agent such as levocertizine or
cetrizine tablets would be helpful.
I hope my answer helps. Please get back if you require any additional information.
Wishing you good health,
Dr Sudhir Kumar MD (Internal Medicine), DM (Neurology)
