I have unexplained itching and burning near my anus

I have  unexplained itching and burning near my anus, it burns more than itches and isn't unbearable but I notice it especially when I think about, which has been more and more as the day goes on I would say more out of personal concern than it actually getting worse as I am an individual who tends to be psychosomatic but I'm unsure of what it is as anal itchy can caused by a variety of things but I really worry it may be psoriasis which I really hope it is not as I wish to join the military as it Will disqualify me if I have it, I would really  appreciate some assistance as I am not currently able to see a doctor at short notice, maybe within the coming week or two but I would really appreciate it someone could either put me at ease or at least give me an educated opinion that way I can potentially start accepting it and trying to figure out ways to cope.

I'd also like to ad that I have some images although the quality isn't the greatest I believe they may be able to at a fair bit of important detail to whatever my condition is but I'm using my iphone to post on this and can not seem to find a way to share those images if at all possible but to add a bit off detail in their place, there is a small area where the skin has spots of a lighter color almost could maybe be considered silvery, they almost look like bumps in the pictures but I cannot be certain as i post this and I'm not sure if the discoloration is a result of an ailment or from me applying pressure or pulling on the area to getter a better look.

Maybe it’s piles? Ever suffered from piles? Is there any blood when you pass stools? Any pain in the area when you pass stools? Any constipation?

I haven't noticed any blood but I the other two yes especially some constipation which results in me spending 1-2 hours a day in the restroom
