Prostate problems

Consultation today , last psa 8.5 , this time 20.4 ( yes I did say 20.4 ) , urology nurse said it’s bizzare , have you had a infection , do you cycle a lot , so got to have another blood test in 4 weeks + mri scan ASAP , not sure what to think other than I should of ignored consultants advice to have consultations every 3 months , mri every year & just had it took away , ive blamed everything on diabetis but who knows , me & mrs can’t think of anything different , other than blood test was at hospital not doctors
But cant see that being the reason it’s gone from 8.5 to 20 .4 , talk about one step forward , 40 back , even daughter who is a nurse is puzzled , even asked nurse if it could be diabetis tablets causing it , she didn’t think so & why didn’t it affect psa last time as was taking tablets then
Anyway look after your health , don’t end up like me !!
