I have had this problem for years, sometimes worst than others. I don't think the doctors really understand how unbearable it can be. I have been recently working with yet another new doctor, and she suggests a possible nerve issue in the neck, and has scheduled me to have MRI done to check. Will let you know results.
Hello,
If the itching started after eating the pancakes, then it can be due to food allergy. Maintain a food diary and notice the foods that cause such itching. Also take some over the counter antihistaminic like Benadryl or Claritin and see if it helps. You can also take some oral steroids after consulting your doctor.
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.
