Why do I experience skin popping on my feet?

It appears that you may be having an issue with the skin on your penis. Irritation, infection, or inflammation can cause redness and pain. Some common signs are itching, burning sensation and tenderness. Do not use rough soaps or chemicals in this area. Keep it dry and clean always. If these signs continue or becomes severe, seek medical advice immediately.

You have some redness near your anus, and using Siloderm cream was a good step as suggested by your doctor. However, since there's no improvement after three weeks, it's important to see your doctor again. The redness could be due to irritation, allergies, or a skin issue. Your doctor may need to try different treatments or do more checks to find out what's causing it.

No, blood donation is not recommended, while undergoing PRP treatment for at least 3-4 weeks.

Keloid scars are marks that are raised and dark because of the excessive collagen. These scars can be highly annoying for people. Utilization of silicone gel or sheets will assist in the flattening and bleaching of the scars. Besides, the application of bio-oil can be even more effective in enhancing the look. Hence, the most important thing is the time and patience to stick to the treatment to be able to see the effects of it. 

Using the cream may have caused your skin to become thin and fragile, a condition known as atrophy. The dark layer you see could be a result of this. Try using a gentle moisturizing cream with ingredients like aloe vera or oatmeal to help fade it over time. Avoid strong products and give your skin time to recover. Always do a patch test on new products before applying them to larger areas. 

Forehead acne is quite common. It can be because of the sebum the skin makes too much as it gets plugged and distresses the follicles. Isotretinoin is mainly used for the treatment of severe acne, so if your doctor has recommended it, it may indicate that your acne has become more severe and chronic. Make sure you are listening to your doctor and feel free to express your worries if you have any.

Those whiteheads on your forehead are probably a type of acne called comedones. The hair follicles become blocked with oil and dead skin cells. Skin conditions can be accompanied by small, white bumps. One way is to use mild face washes with salicylic acid or benzoyl peroxide which can help remedy the clogged pores. 

Canker sores are small, painful ulcers that are so troublesome that one can find it hard to speak or eat. Stress can be a possible reason for them as well. To promote healing, try rinsing your mouth with salt water about three times a day. Try to avoid spicy and acidic foods that can aggravate the sores. Regularly brushing your teeth and mouth can also speed up the healing process.
