pinworms are always a possibility and you can certainly have a pinworm test to see if this is the underlying problem. pinworms can be spread to adults by children especially those with less-than-optimum handwashing habits. itching can be caused by improper hygiene allergic reactions to soaps improper rinsing during a shower allergic reaction to perfumed toilet tissue laundry detergents and dryer softener sheets. skin tags tiny fissures or even small hemorrhoid can cause itching. any skin condition especially a fungal skin condition can cause itching. if your problem continues you will need to see a medical professional. while having someone look at your bottom may seem embarrassing it is not considered a problem for clinicians. they do it all of the time. why suffer? get some help if you cannot solve this issue yourself.
the last few months my anus has been itchy before i go to bed. i am usually busy in the day so i am wondering if i am itchy all during the day but only notice it at night (when i'm almost always laying stomach down while using the computer). i also had mysterious itchy red dots on my legs 3 years ago and i usually still have one or two on my thigh at any given time. could unseen ones on my anus be the cause of the itch? or is my anus just itchy because i almost never scratch (a fear of pinworms makes me almost never scratch)?
