I Just Had A Picc Line Inserted. I Have Practiced

I just had a picc line inserted. I have practiced yoga for 15 years, twice a week. I have been cautioned about raising my arms above my head & some have said I should not do down dog. I'm unable to find any knowledgeable medical advice about this -only from lay people about their experiences. I'm wondering if these yoga poses are likely to cause the line to become dislocated if I move slowly.
