My father was diagnosted at 79 with prostate cancer.  He was administered Firmagon androgen deprivation injections and underwent internal (seed implants) and external radiation treatments.  He had the anticipated side effects during that time, but now, 2 years later, is having extreme fatigue and chronic testicular pain.  He has mentioned his symptoms to his general practitioner, oncologist and urologist, without any response as to cause or possible treatment.  I dont know what his current PSA is, and am not aware of his continuing to take any androgen deprivation medications.  Are these current symptoms side effects from the injections and/or radiation, and is there anything that can be done to help alleviate them?
Hello and welcome to Chat Doctor, Presence of fatigue and testicular pain, with a past history of prostatic cancer has to be investigated. A serum PSA level needs to be done.PSA levels increase exponentially in case of recurrence or metastasis of prostatic cancer. Appearance of fatigue can be due to distant metastasis. Chronic testicular pain warrants examination of the testis. A ultrasonography of the testicular region is also required to look for any enlargement of the testis. These symptoms are unlikely to be due to radiation exposure or hormonal treatment. Consult your treating doctor for clinical examination, relevant investigations and management of the problem. Thanks and take care Chat Doctor.
