In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
You have a medical condition. You should refer to your Physician for medical help. Therefore, there will be no need to take a shower. The consequent concerns will also be addressed, Insha Allah.
And Allah Ta’āla Knows Best
