I have a family member who's experincing trembles after laying down at night and early morning, just before urinating. However, after relieving themselves the trembles go away. Has anyone experienced this problem before as a diabetic or non diabetic bladder issues. Where can this person be directed to? (Nerve damage at the end of the bladder will cause this damage, bladder spasms. They take Pravastatin also. Has anyone ever experienced this issue? If so please help.
