Welcome to Health Care Magic
There should be no problems. If you have no problems now, there won’t be any problem from the travel itself, barring any accidental event... Modern aircraft are pressurised cabins.
A few tips may help – Avoid Physical and psychological tension.../ Get ready in time; don’t hurry / Do NOT lift heavy weights – use the services of porter and trolley / Have your report and emergency medicines in hand baggage / keep a supply of drugs enough to last a week longer than the period / Avoid junk food / Avoid prolonged sitting in-flight to avoid pulmonary embolism
– try to move your legs and feet and walk
Bon voyage / Happy marriage...
