Patient discussion about sound waves
Q. what causes the sound of cracking noises in the head all the time it was said i had acute sinusitis but honestly i think it is more . I don't know why i have cracking noises in my head . I am very concerned about this also my neck is always stiff feeling and aching all the time. . My eyes are very tired and i see blue spots and they hurt behind the eye very badly . I have headaches very often
A. wow...that really sounds serious...i have chronic sinusitis and i can tell you i had horrible headaches but nothing like you describe now. i would strongly consider going to a hospital and checking it out...

Q. Atkins diet? Is it good as it sounds? I'm 17..about 5'2 145 lbs.. I need to lose as much weight as possible in 3 weeks ..Anyone know what kind of results i can expect on atkins?
A. I originally did Atkins 4 years ago. I lost 30 lbs in 3 months and kept if off about a year. I gradually started cheating more and more and exercising less, until now it's all back. Atkins works for me because I naturally crave protein. I am ok with eating lots of eggs. But, the weight only comes off if exercise is included in the plan.
Q. what kind of uses the medicine do with computers related to ultra sound? how does the computer helps the doctors in the ultra sound? what do the compuers use for?
A. the computers help the doctors (in ultrasound cases) to interpret/convert the ultrasound waves into a specific imaging showed in the monitor. by that a doctor can find what is normal or not inside the patient's body.More discussions about sound waves
