Hello, I am female, 67 years of age, 5ft tall and 70 kgs (I have regular cortizone for my serious asthma ) I am also being treated for thyroid problems. My question is - For very many years I have suffered from severe itching between my spine and left shoulder blade. Have tried everything I can think of without success. Is this possibly due to my thyroid problem or could it be notalgia paresthetica (I have only just heard of this problem) I have been told I have a slight curvature of the spine - could this be the cause of the notalgia, if that is what it is? Any ideas please and any thoughts on making my back more comfortable. Thank you very much.
