What could be causing my severe itching?

For a couple months now I have had a lot of problem with my skin itching. The itching is more prominent on my upper arms, torso, scalp and legs. There's no itching on my palms or the bottom of my feet, and little to no itching on my forearms or groin.

Also, among the prominent itching areas are clusters of small bumps, barely noticeable unless one is looking for them. They can be distinctly felt by rubbing my hand over that area, it's clear that they protrude from the skin, but they're certainly not noticeable to others.

I should note that the itching is not the "scratch yourself raw" kind of itch, it's just like a normal itch. Scratch it for a sec, and you're good. But it's just how often the itches reoccur that makes the whole thing quite distracting and uncomfortable, 24/7.

One more thing. I don't shower. Very rarely. I shower once or twice a month.

I went to the doctor a couple weeks ago. He thinks it's something with my follicles, I can't recall precisely what.

Out of room.

Before I read further that you state you've been to a doctor, I was going to say scabies. I don't know anyone who has suffered the same problem but - you don't shower? No baths or showers for weeks? Maybe it's dead skin cells irritating you.

Showering often is important to keep your skin healthy. Sometimes, the skin gets dried up and they get itchy. Put on some moisturizing lotion. and for your health, taking a shower more often will improve your hygiene as well as removing some of the dead skin cells and dirt on the skin that have collected there for a long time.

Since you shower rarely. I hope that when you DO shower, you scrub hard and clean to get rid of any possible parasites especially bed bugs who targets people who shed a lot of dead skin cells. I recommend changing that showering rarely habit.
