A itchy redness or rash has appeared on my inner foreskin recently. Antiseptic cream helps but it never goes away. No other symptoms. Should I worry?

Balanitis. Sounds like Balanitis. One can try some over the counter steroid and antifungal creams. You may have to get a prescription. Depending on your risk factors and the size of the 'bumps' one could consider herpes.
