You should see your Doctor. Most of these symptoms i.e. shortness of breathe can be thoses of Restless Leg Syndrome (RLS) which can be a sign of poor circulation.
And with poor circulation, your heart and other organs can be deprived of much needed oxygen. When oxygen is not getting to organs sufficiently, they may not function properly and begin to fail.
You should be evaluated by a Physician when you are suffering from what could be a fatal condition e.g. RLS. Seeking a Physician soon, can greatly reduce the risk of futher damage of organs and the way they function.
Hope this answers your question!
