Yes you can. I wouldn't go over twice a day though until you
find out what is causing your feet to increase with pain.
Epsom salts are just for relief of discomfort. If your PAIN is being generated in the spine it will not block that. But magnesium can help with vascular issues (circulation). That is called ischemic pain as opposed to pain generated by inflammation (arthritis), or compressed nerves. I've lost track of your history, other than the thyroid issues. So do pay attention to your worsening feet as a sign that something else may be going on, etc.
Do you have compressive issues? Have you tried Biofreeze?
Lidoderm patches? Do you have increased PN in the hands as well?
