If you think they are Fordyce spots, they probably are.
It could be too much soap, dry weather, dry skin, etc etc - the list is endless. It could also be an allergy to the soap you are using. Try a scent and dye free soap. Use something gentle. Make sure you are rinsing it off your skin well, too. Unless you do things like construction or work in a field where you get really dirty, you probably don't need to use soap every time. If you work out, try rinsing after.
Use scent and dye free laundry detergent, too. Make sure you are changing your sheets regularly - weekly is good, but at least every other week.
You may have to play around with things to see results.
Also, if I use soap when I shower, more than two or three days in a row my skin seems to itch. So a doctor suggested that I don’t use soap everyday. Could this be because of using too much soap? Or dry weather?
To be honest I can’t tell if the sensation in my testicles is related to my stiff back or not.
The bumps on my penis and testicles are spaced out. They look like the pictures on fordyce spots. They don’t hurt, or have any redness or anything. They are yellow. It’s been about two days since I first noticed them.
Just to add - the burning or tingling sensation seems to be when my testicles are rubbing against something. When they are not in contact with anything there is no burning. I am a little overweight and I seem to sweat in summer.
There seems to be itchiness at a bunch of random spots like on my shins, belly, nostrils, eyes
Just wanted to add - based on pictures on the internet, all the bumps look like fordyce spots. There is no blood or puss or pain on touching, I don’t have any pain in my penis or testicles.
But I have itching in random spots all over my body, face, where my leg and pelvis meet (the joint area)
