Any electrolyte imbalance can cause cramping and potassium (what doctors call K), is an electrolyte.
I hope the potassium puts you in the pink again.
thank you very much for your answer, i went to the doctors and had numerous tests done, all of which came back normal apart from one thing which is i have moderately low potassium in my blood so i am starting potassium supplement pills & hopefully this will be the answer to my seemingly random pain and cramps.
Chloe, thank you for writing.
Yes, it is possible to have rheumatoid arthritis at age 16, however, it is not likely.
Most arthritis victims discover their disease at age 50 or above.
And of most importance, arthritis sufferers have a history of arthritis in the family. This is a hereditary disease.
Pleurisy associated with rheumatoid arthritis is occurs in severe cases and only in the advanced stages of the disease. You are not old enough to have developed pleurisy from RA.
A simple answer to your question is to see your doctor for an examination and blood test.
Let me finish with an observation. Often, when we suffer unexpected and misunderstood symptoms, we become hyper-aware of the small pains, ticks, twitches, and other somatic phenomena that are normally below our awareness level. This hyper-awareness can cause anxiety, which in turn causes more somatic phenomena.
It is a cycle of worry that can spiral into a serious syndrome known as a psychosomatic or somatiform disorder.
Often these symptoms and cycles are related to social or psychological events that we've experienced recently. At your age, some may call these symptoms "growing pains." There may be other explanations.
From the detail that you expose in your post, I believe with certainty that your pain is very real, but I suspect that your related somatic experiences may be due to the hyper-awareness and anxiety cycle I've related.
Thus, for you at 16, it may be best to talk with your parents about seeing a physician for an annual physical. Everyone should have an annual physical, whether they're sick or perfectly healthy. While you're alone with your doctor in complete privacy, mention your worries about arthritis, and let her help resolve your fears by making the proper tests.
If there is something going on that needs treatment, then by all means follow through. But if you come out with a clean bill of health, I suggest that you to limit your concerns to those of a normal and healthy 16 year old girl.
