OMG! I thought I was going crazy! I have been itching for 8 years! At first Clariton or Zyrtec helped. Then the itching came back. Last year, a dermatologist prescribed Naltrexone which helped for a year. It was a miracle to me, but now the itching is back!!!!! worse than ever! I sleep every night with ice packs on my arms. Every where we go I have a ziploc bag for ice! It is a miserable feeling! I have been to several different doctors and I still believe it is a nerve ending problem.I am going to try the Lidoderm patch and sunscreen. Anything that will give me some relief. I am just so glad that I am not going crazy. Every doctor has told me it is anxiety. I already take Effexor so that should help. I will keep you updated and let you know if anything helps me. Please keep everyone posted if something works for you!!!!
