Good morning @rashida. As the saying goes, "I feel your pain" and the frustration of trying to find something that works. Is there any way you can see a dermatologist in Toronto?

How long have you had this unwelcome and irritating "itch"? I can see that you have tried many products seeking relief. Where does the itch start? On your arms, legs, scalp? Do you have a rash also? And may I ask, do you know if you also have symptoms of neuropathy?

I have been fighting what I just call the ITCH! for a couple of years. You must be careful with products. I am going to attach a link to my most recent post. I have some relief right now by using Tacrolimus ointment .01%. It totally works but you can't use it every day as the ingredients include some strong elements. You will need a prescription.

I see you have connected with @tim1028. His recommendation to moisturize, moisturize, moisturize is a good one and coconut oil is a good "comfort" candidate without allergens.

Here is a link to my last post. Since I wrote that I have found that my external antagonists are Fragrances I and II. You may need to change some of your daily cosmetic and even laundry products. Even fragrance masks can be a culprit.

That's enough for this morning. Let me know what you think and if you want additional explanations. I am wishing you quiet sleep and a sunny day and will help you in any way possible. Here's the link.

May you be free of suffering and the causes of suffering.
