Does Protruding Abdomen, Constipation And Swollen Feet Indicate Sign Of Hypothyroidism?

I need help with what is problem! I have,been suffering for years. Seen MANY doctors-no true diagnosis. -tilted walk/ left leg longer (I ve had several injuries/falls and broke back-T3&T4, from auto accident) -abdomen protrudes -frequent urination -frequent constipation -swollen feet/ankles -weight gain -tendency to be cold -..... I could go on and on, but wondering if this is hypothyroidism?? Can it cause muscle weakness? And all I just mentioned? What diseases can it mimic? MS? Lyme? ?? Thanks for feedback!
