Foreskin as become fat and some cut marks on it, not able to move my foreskin back and if I touch there I feel burning sensation, the problem is from one month ,please suggest some medicine please

It sounds like you may be experiencing balanitis, which is inflammation of the foreskin. I recommend using an antifungal and anti-inflammatory cream like Clotrimazole 1% cream. Apply a thin layer of the cream to the affected area twice a day for 1-2 weeks. Additionally, you can take an over-the-counter pain reliever like Ibuprofen 400mg to help with the burning sensation. Make sure to keep the area clean and dry to prevent further irritation. If your symptoms do not improve or worsen, please follow up with a healthcare provider for further evaluation.
