### input:
40 yr old male.Sometimes my hip seems to nearly lock up, and I have to lean to that side and put stress on it to make it pop. Hurts a little, but I get my range of motion back. In addition, after sitting for maybe a short as an hour, deep inside my pelvic region on both sides will pop as I flex/tighten my muscles to sit up prior to standing.I fear that I may have a fractured hip tho I guess it could be mis aligned. But its the deep pelvic poping that has me concerned. I can only find references similar to what I feel as things a woman feels during pregnancy. And I assure you, I am not pregnant :-). All of my joints are becomeing easier to crack, as if I live a stress free life ( which I doubt ) and my muscles around my joints seems to have relaxed inadvertently to the point that a slight movement on my part causes them to pop. Most disturbing of all is that I can pop my sternum by taking a deep breath stretching my shoulders back.Is this some kind of arthritis disease? Could my body be releasing relaxin uncontrollably for no reason? Some joints are painful like my knees and shoulders and hip, and others are not, like my ankles,wrists, elbows, lower and middle back and my sternum is pain free.  thanks

Hi thanks for contacting Chat Doctor... Noted you have mainly pain at hip joint. Yes if you are overweight then arthritis might lead pain.... With advancing age and if calcium deficiency then osteoporosis like change might lead such presentation... For these condition to rule out x-ray of hip joint done..... If multiple joint paining as you have mentioned in last also involvement of knee and wrist joint then rheumatoid arthritis might rule out by RA factor if suspected.X-ray will also rule out about any fracture or inflammatory arthropathy.... Take calcium tablet if hypocalcemia. Vitamin d deficiency also corrected. Take care. Chat Doctor.
