Hi, im 54, ive had three low back surgeries with multiple hardware installed and one cervical surgery with multiple hardware, donor bone and plate installed. I have ddd, stenosis, scoliosis, arthritis and chronic nerve damage. Within the last couple years I started having uncontollable muscle twitting in my arms, leggs and stomach muscles. Within the last few months the twitting has worsened both day and nighttime, I have also developed bladder control issues, I need to go at night time every one to two hours, I have also developed an urgency to go and leakage. What do you think is going on?
