I am Monica DeJesus, care provider/grand daughter for Irma. The wheel chair that she got last year, the brakes aren’t working as they should. Can you help me with this? I also wanted to inquire about Pure wick external catheter. She will not take her medication for urinary retention as she should, because of the severe ringing in her ears. I try my best to make her daily living as easy as possible, but she makes things very difficult at times. I feel that this external catheter may help her a great deal.
