I have had itchy scalp for about 8 weeks. I have T2 and on Metformin. My dermatologist could not figure out what the problem is and has put me on anti-pruritis and anti-histamine medications. My blood glucose is in control and he seems to think it was a shampoo or hair dye I have been using for 10 years. He never looked at my isolated itchy spots on my body: back, legs. The topical sometimes work, sometimes not. It seems to work better with the red itchy spots. I also have symptoms of urination urgency, but my psa is normal, or very slightly elevated, 4.2. The medicated shampoo sometimes heap with the itching but not a lot.
My questions are: Is there any blood test to diagnose this itch? Any allergen test that I can request to be done? I know it could be from dry skin, but I also use a cream specifically for diabetes. I read about not taking a hot bath or not scratching. It is hard to do, especially when one is sleeping; scratch, scratch, scratch. I have never had this problem in my life, and I am trying to figure out what the cause is, a number of possibilities:
- diabetic dry skin, not controlled
- growing cactus as a hobby and eating their fruit, tunas, to lower glucose level (prickly pear) and got pricked quite a bit in the process
- some kind of food allergy
- allergy to dust in my house, full of clutter
- stress and emotional outburst
- working and painting my cars, the material and paint used
- drug side effects: I now take seven everyday, three for T2, 2 for depression (Double Ds), one anti-histamine and one anti-pruritis Rx. The liver might have a hard time breaking them down and detox.
- a combination of symptoms
Any suggestions?
