Hi @Saram - welcome to the forum! Feel free to put up any question re anything! I am sure someone will have an answer or suggestion for you!
Where abouts are you (State/town) as someone may be able to suggest another Onc near to you.
I had the same situation with my original Onc as well - I just didn't 'gel' with him either and actually found him to be very dismissive of my concerns re the side effects of the AI tablets that I am on. He just didn't believe me! I actually saw him rolling his eyes the last time we met, with me once again, mentioning the nasty side effects and how to mitigate them! So I have changed to a lovely lady Onc who is terrific (tho she is currently pregnant, so will be out of the picture soon for some months.) Funny that - my GP has just given birth as well, so looks like it is catchy!
I hope you are able to find someone you get along with - I think it is really important to be 'confident & happy' with your medical team, as we'll be with them for many years to come!!
Take care & all the best for your treatments xx
