Complications of Low Sodium. Like potassium, having slightly low sodium levels may not cause any distinguishable symptoms. Chronic low sodium levels are much more likely to sneak by undetected than sudden drops in the electrolyte. Possible symptoms of low sodium levels include muscle spasms, nausea, fatigue, irritability and headache.
Applications for Social Security benefits can only be processed a maximum of four months before benefits are scheduled to begin. Thus, the earliest you can apply is age 61 and 9 months, and you can expect to receive your first payment four months later, the month after your birthday.
(This maximum gets you to 12 months before your application date, plus five months for the waiting period, so your earliest your effective onset date can be is 17 months before the application date.) In this case, the earliest that you can become eligible for Medicare is one year after you apply for Social Security disability.
