Matthew Stewart2 said:To clarify, the itching I am inquiring about is concentrated around the left elbow, extending upward toward the shoulder and down the forearm. Due to relentless scratching, the skin has become intensely crimson and possesses an elephantine texture to the touch. My mother observes that when she manages to resist the urge to scratch, the sensation seems to subside—though, quite logically, the act of scratching likely just exacerbates the underlying inflammatory process. Separately, she is experiencing a distinct type of itching in the groin area which she maintains is entirely unrelated to the irritation on her arm. Furthermore, she suffers from seborrheic dermatitis in her ears, which is also quite itchy. One ear has actually swollen to such an extent that her hearing in that ear is noticeably impaired. A few years back, she dealt with shingles on her scalp, and she recently noted two spots near the groin that looked suspiciously like herpes lesions as well.
My mother is sixty years old—navigating menopause, naturally—yet she remains exceptionally vital and energetic. Regarding allergy testing, she did undergo some screening, but the clinic she visited simply lacked a comprehensive panel of allergens. She has already consulted sixteen different doctors, and we are still no closer to a definitive answer.
She is currently preparing to eliminate both coffee and tea from her diet, a task that will be quite difficult given that she tends to have low blood pressure!
Olivia Garcia60, my thanks for your previous post!
Regarding Hodgkin, which some people brought up...
Does your mother get sudden fevers often?
Does she sweat at night? Get thirsty at night? Is her arm swollen?
If the answer is YES, then it could be Hodgkin lymphoma and you need to go for further testing immediately. If the answer to all those questions is NO, then it isn't lymphoma and you don't need to worry.
Like you said, the redness in the groin has nothing to do with the elbow. That groin itch is most likely just skin irritation from clothing. The seborrheic dermatitis isn't a major factor either; that's pretty common.
The itching and rashes on the elbows are extremely common because the skin there is so sensitive. This happens a lot during high summer temperatures (that part of your story fits perfectly), and these itches can last for months, causing swelling, redness, and skin damage—especially from heavy scratching. I think that's exactly what your mother is dealing with. Since this isn't a generalized itch over her whole body, the diseases I just mentioned can be ruled out.
