Penis is itching under foreskin has been 6 days no rash or sores etc are present very annoying help ?

Under foreskin itch: This could be due to an infection you can not see - either bacteria or fungus. Also are you taking any other meds since sometimes certain rashes like a fixed drug eruption can occur on the penis when you are taking oral medications. You need to discuss this with your physician since other issues like lifestyle, hygiene, can also affect the foreskin.

Tight foreskin?: This can happen if your foreskin does not retract easily. Prescription strength steroid cream might help loosen foreskin to permit satisfactory washing ; drying of inner foreskin ; glans. You might need a circumcision or prepucioplasty if this continues. You could get this done under the nhs as ur symptomatic.
