Aside from itching, have you noted any change in the skin?
I sent an information request but you haven't provided. I am waiting for you to provide an information before giving you an answer if I can.
By the way, you will only pay if you accepted an answer. As I notice, you have deposited in your account but but no payment have been made yet for any question. Anyway, I will let the moderators know to clarify things with you.
Have you tried any topical corticosteroids?
What psoriasis medication have you used?
Can you please describe further how the skin looks like? (red?brown? bluish or like violet? flaky? any blisters?
Is the itching and peeling continues or on and off?
May I know what is your job?
With the descriptions you provided, I would suspect chronic dermatitis as the possible cause of your condition which can be helped by steroid treatment.
Since you have been suffering from such itching for 3 years, If you have not done yet, I would think of doing an allergy test to determine what triggers such skin reaction. I would also consider skin scrapings culture and sensitivity test and perhaps a skin biopsy.
Please discuss that with your doctor.
I cannot think of any other possible causes so I will opt out to let other experts who may have more ideas to help.
Good luck and take care!
You can have dermatitis anywhere in your body. It is usually a local reaction to any irritant.
Scabies usually have pimple-like irritations or rashes and besides it seems to be too long to have scabies for 3 years without recognizing it. The other members of the family are supposed to get the infection as well if scabies persisted all of those years.
It would be unusual for betablockers to trigger such intense itching unles you have hypersensitivity to the drug. If you are taking maintenance dose of any beta blockers, an allergy test can show if it is related to the itching you have.
Psoriasis usually have red patches with silvery scales covering but it is possible to such characteristic pattern.
The two both achieves improvement from steroids. You can try over the counter topical corticosteroids however if it does not show any improvemet, stronger prescription topical corticosteroids may be required.
The difference between the two is that psoriasis for the meantime do not have real cure and it has the tendency to come and go. Dermatitis however can be treated and cured and recurrence can be avoided if the factor that triggers the reaction is identified and avoided.
You're always welcome. I hope the source of that itchings can be traced and you get some relief. Take care and good luck. Thank you for using Just Answer.
