Restless legs from oxy withdraw,have same inner restlessness&inability to remain still coming from my testicles with slight ache.what is this?

Testicular akathisia: Not uncommon. Totally makes sense that you are having this also due to OxyContin/oxycodone withdrawal. Make sure you are taking a multivitamin & eating foods rich in B6 & polyunsaturated fats. Ask your supervising provider if s/he thinks propranolol would be helpful to relieve symptoms. Benzos useful, but would be hesitant to use those given your circumstances. Perform self-check for mass as well
