Hello dear, Ibuprofen is given to bring down the pain and inflammation.It can be stopped once the wound is healed,and pain&inflammation has gone.Iron supplements may have to be continued for a few months to replenish the loss.Your treating doctor will guide you in this. Your low apatite,can be from the insult caused by the major surgery you had.It will become normal gradually in a few weeks.Take plenty of fruits and veges to have adequate vitamins and minerals.I guess the surgery followed an accident,and not for conditions like ITP/thalassemia. Wishing a faster recovery.Thank you.
