The fibromyalgia is likely to be related to your age, and changes to your hormonal balance. It can be expected to increase your SENSITIVITY to the pain, (whether or not the stimulus causing the pain has actually increased objectively).
Arthritis will cause inflammation of the joints and ACTUALLY cause some of the pain that you are now also more sensitive to.
I am sure that you will find it beneficial if you can increase the amount of light exercise that you take, perhaps a bit of swimming (which helps to support the joints uniformly during exercise) or gentle dancing to music that you enjoy listening to.
However, I think you should discuss this matter with your Doctor and follow any advice given, regarding a suitable exercise regime. That way you can minimise the likelihood of exacerbating your condition - particularly if you have suffered any long term joint damage due to your gymnastic activities.
"Bones cracking" is usually caused when bubbles of air, (that occur naturally in the synovial fluid that lubricates the joints):
are forced suddenly, under pressure, through a very tight gap between the cartilage that cushions the ends of the bones forming the joints.
I suspect that it becomes more noticeable, in more joints, as we get older: when we tend to become less flexible and often become overweight.
The reduced flexibility and thicker fat deposits cause the joints to bend under a greater strain, consequently forcing the air bubbles to move more suddenly, and under greater pressure, through the tight gaps between the ends of the bones, thus causing a louder sound.
The cracking sounds have almost certainly occurred throughout your life. You just did not notice them so much when you were younger, possibly thinner, and more flexible.
It is not really known what actually causes fibromyalgia, rather, it often seems to be related to changes in hormone levels, and thus can be expected to be more likely to occur in women around the age of menopause. An endocrinologist will be able to test to see whether your medication remains appropriate in the light of (what I assume to be) recent changes in your symptoms.
Okay but when I bend or even just getting out of bed or any slight movement my bones especially my knees bends and it's not very comfortable it's sort of hurts and I do have fibromyalgia and arthritis could that have anything to do with it
When I was younger I used to be in gymnastics I used to be able to fold myself backwards I was very very into gymnastics and yes I noticed my bones cracking for a long time but now I'm 48 years old and I feel him even more now
You said that fibromyalgia may be due to hormones well I had a hysterectomy 20 years ago and I've been on estrogen pills ever since
Are you a dancer? If so, then that's normal.
No I'm not a dancer
