i have extreme muscle weakness in my legs, more in my left leg with swelling

Posted by Beck

Over the last year I have lost strength in my muscles most noticable in my legs. My left leg is very bad and has extreme swelling along with it. It is to the point that I find it difficult to climb stairs and simply walking a short distance is a task. I have been getting light headed and have had over all extreme pain in my body. I have experienced my heart racing and a feeling of fullness in the bottom of my throat. If this continues I am afraid I will not be walking in a few moths. I have seen specialists and I do have arthritis in my knees, my lower back and neck. But the doctors say it is normal for my age and requires no attention. I am 48. I have asked my doctor to check my heart and he says he does not think I have heart problems. I feel awful. I have stress and extreme bouts of anxiety. What is going on?
