I am not an AME but my understanding is this drug is not permitted due to its side effects. The drug is well gone from your system and there should be no current issues. Dysaesthesia is a strange word to use for pain from sciatica. Sciatica is OK but beware the term dysaesthesia can be associated with some exotic neurological issues. Assuming you have none of these I would think sciatica will cause less hassle - but always tell the truth!
