Can low testosterone 170ng/dl be d cause of very bad calves pain an back of thigh muscle pain,ive pain 7 days a week,but since nebidio it's all gone?

Not a usual : reason for calf pain but tell us how you are in a few weeks. See a vascular doctor if pains return

No: Calf pain not related to testosterone, usually resolves on its own. Tests for "low T" are not reliable. Effects of testosterone injections are almost all placebo. See an endocrinologist before you commit yourself to a lifetime of useless injections.
