Januvia and leg pain

Have been on Januvia for 3 weeks, Very bad left shoulder started about one week into treatment. I initially thought that I had slept on my shoulder "wrong". Left leg pain started last week. Lower leg feels tolerable sitting however when I stand & walk, get shin splint type pains. Shoulder is improving & leg pain intensifying. I called doctor's office this morning and relayed symptoms to the nurse. I told him that I was discontinuing Januvia until I heard otherwise. He took my number but physician did not return call today. I find it odd that there is no mention of this type complication in the patient information handouts. I have taken Motrin, Aleve & Extra Strength Tylenol without relief.
