It is important that a DVT is excluded (at least by clinical examination, if not by doppler) as your past history puts you in a slightly disadvantageous position. However, if you are now not taking tamoxifen
etc then the risk is low, but if the flight exceeded 6 hrs without much feet exercise, then it is better to exclude a DVT.
It is unlikely a reaction to ciprofloxacin
, unless you have a past history of quinolone allergy
. The rash
also means a DVT must be exlcluded.
If the rash is itchy, then venous pooling with dryness of skin can cause a rash, when antihistamines will help.
But I would still recommend getting this checked out.
