I have no results at all. Is it possible that the Diclofenac (Cataflam) for foot injury affected the results ?

If you are not satisfied with your surgery results, it is best to follow up with your doctor and express your concerns.  It would be unlikely a foot injury and medications would affect your results.

It's very unlikely that Diclofenac affected the results of your transplant- hopefully at the time you would have mentioned to your doctor(s) about all your health issues including that you would be taking it while recovering from a hair transplant surgery. If so they wouldn't have prescribed it if there were potential effects it could have.

It is unlikely that diclofenac would cause you to have no graft take.  There are several potential causes, some of which require treatment.  I suggest you return to your surgeon for evaluation and to review preop photos and go from there. 

If you are concerned about your results, see the doctor who did the surgery. They should compare before and after photographic results with you. Hair transplantation if performed skillfully and assuming correct diagnosis (of hair loss was made), will rarely fail.

If you had a hair transplant failure, you need to go back to your doctor and not second guess the cause of it. Ask your doctor
