I Take Oxycodone 5/325 1/2 3 Times Daily For Severe

I take Oxycodone 5/325 1/2 3 times daily for severe headaches along with 2 Midrin twice daily and two Topmaz twice daily. I am prescribed a full Oxy 3 times a day, but am afraid of addiction so I suffer through the pain that is with me unless I am lying down. I have begun to have digestive issues. Feeling like I have to have a bowel movement all the time, but am only able to go a small amount every half hour or hour and it is accompanied by abdominal cramping much like constipation, but my stool is usually loose. Cause of headaches are being determined by neurologists to date they have found 7 lesions on my brain and 5 types of EEGs have come back abnormal. Trying to figure out what is going on with my digestive track. I am also displaying symptoms of a pretty bad bladder infection even though I take a daily preventive antibiotic for just that. It is not unusual for me to presnet bladder infection symptoms when I am constipated.
