I have had the same symptoms since I injured myself at home trying to open a jammed door with my shoulder. I had incredible pain on side of my ribs and actually felt like ribs shifted.I have had X-rays and nothing can be seen on them. Since then I have been experiencing the charly horse type pain when stretching, dressing and sleeping. It effects my toes, legs, chest and back.
Hello,
Muscle spasms can be due to alterations in the balance of salts in the bloodstream (such as a high or low calcium, sodium or potassium level),neuropathy(esp in diabetes),hypothyroidism, nerve compression, and multiple sclerosis,spinal cord injury,cerebral palsy or stroke.
My advise is to consult a physician and rule out the above medical conditions by thorough investigations as without physical examination and investigations, pinpointing a diagnosis is tough.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
