Adrenal endo recommendations please

Has anyone seen an endo in Kettering hospital they could recommend I’m new to the area and as I’m getting nowhere fast here,(just cancelled private endo),I’m thinking I may as well try my new gp and see if I can get a referral as private endo looked at saliva tests and said I need to arrange a short syncathen test and more bloods but I know this is going to cost me a small fortune and I’m not very confident about all the travel involved either,I’d rather stay close to home right now and try make the nhs work for me.any help or suggestions much appreciated as always.xx
