"Not satisfied with treatment/follow-up"

Visited the Dermatology on the 5th July 2016 and one month later received a letter with the good news that there is no evidence of any malignancy in the affected area,, letter ending " No further action is needed" apart from some antibiotics. I would have thought they would have at least followed it up to find out how it was. It's now 6 weeks later, three further visits to a GP and more antibiotics. My GP is sending a referel letter to Dermatology but as I was dismissed by the hospital I could wait months to see them again. I do appreciate how very busy they are but a follow-up appointment to check would have saved my time and the GP's time, I am now in a worse situation then before.
