I am a 46 yr old female who's had back pain for years.My symptoms are sore left hip, tailbone cracking,bottoms of feet hurt, upper thighs REALLY hurt and have "dents" in the muscles,im fatigued most of the time and also have tiny muscle twitches all over. My knees also crack. Sometimes to get any relief at all i lean back on my butt while holding my knees until my tailbone cracks, usually 3 or 4 times. Help :(
