Hello, For The Past Six Months I've Been Taking A

Hello, for the past six months I've been taking a low dose of fosamax. In the past I tried the higher dose and had dyspepsia. I walk regularly for my osteoporosis, usually 4 plus miles daily. Today after I got home I began to notice hip pain which doesn't feel muscular. I understand this could be a side effect. Do I watch and wait and if persistent perhaps have an X-ray?
