i am an 18 year old male and in the summer of 2007 i noticed that i had stiffness in my back and neck and with the stiffness there was severe pain. i also noticed that my back and neck crack alot. i went to my doctor and got xrays done on my back and neck and he said he found nothing wrong. he did no other tests other than the x rays. over the last several months ive noticed pain and cracking in all of my joints, including fingers, toes, back , neck, ankles, wrists, hips , elbows and knees. i noticed warmness on certain parts of my body and ive noticed that i itch alot. i have numbness on one side of my face sometimes and my jaw gets really stiff and when it cracks, the numbness goes away for a short period of time. ive talked to some experts without getting physically examined. one expert mentioned lyme disease, hepatitis, and meningitis but i dont know what could be wrong. ive noticed my joints are stiffer and more painful in cold weather and i also stay sick alot with colds. i have numbness and pain alot in my joints and sometimes my arms have weakness and stiffness that hardly allows me to move them. thanks for your time doctor.
