Intensely itchy arms

Sorry to hear that, itch can be unbearable at times. are you taking any medication that might be causing it , has your GP referred you to a dermatologist?

Hubby takes an antihistamine for itchiness due to his diabetes. This might help?

I suffer from asthma and allergies. One night for no apparent reason, the outer skin of my left ankle started to itch real bad. Fortunately I have creams of all sort in my medicine box. I used Nivea anti-itch cream - it eased a bit, but I had to resort to a steroid cream which I had got from Spain. That sorted it.
See your Doctor is my advice. Itching, eczema and asthma go together. My sweet little grandson has a similar problem. My heart aches when I see him crying and scratching his legs . I slather him with Diprobase. It helps him.
Moisture, moisture , moisture ………

Have you tried different antihistamines as some are better than others for specific problems.

Has your doctor suggested a blood test? If topical application does not help it is possibly caused by an underlying problem This happened to me.

I have itchy legs caused by limphoedema. My right arm, neck to my chin and my chest have driven me crazy. Very recently. Firstly I applied cold cream and that moistened the skin and helped slightly. A couple of hours later I applied Eurax from Amazon which I apply to my legs and that definitely helped.

My neck and the top of my right arm are driving me crazy now and the neck is bright red with my scratching.. I have a telephone appointment with a GP tomorrow to start long term anti histamines.

Poor you. Yes I’ve suffer ever now & then, but inside my upper right arm (not arm pit). Drives me nuts.
I never thought of taking an antihistamine. I just put on a dollop of emollient during the night, which seems to ease it.

I get really bad itches now and then. I find that Lanacane or Eurax cream, both available either off the shelf or over the counter at Boots, work pretty well.
