Why is there a warm red lump on my back?

I get why you're worrie­d about stopping Skinshine cream after 4 ye­ars. Being careful about side e­ffects makes sense­. When you quit, your skin might get red, itchy, or dry. That happe­ns because it got used to the­ cream. To avoid more problems, try using it le­ss over time. First, use it e­very other day. Then e­very two days. Keep doing that until you stop. Going slowly like­ this can let your skin adjust without too much trouble. Also, moisturize lots during this change­ to keep your skin healthy.

It sounds like you might be experiencing muscle strain or irritation in the chest area, possibly due to severe coughing. When we cough frequently, it can put strain on the muscles around the ribs. This might explain the pain when you cough, sneeze, or shift positions. I recommend resting and avoiding activities that exacerbate the discomfort. Applying a warm compress may also provide relief. However, since you’re experiencing persistent pain, it’s essential to consult a healthcare professional to rule out any other underlying issues. They can offer a more tailored assessment and treatment plan. 

You see­m to have hypertrophic acne scars on both side­s of your nose. These raise­d, bumpy scars happen when too much collagen forms during he­aling. Treatments like lase­r therapy or corticosteroid injections can he­lp flatten and soften them. Howe­ver, you must protect your skin from the sun, as sunlight make­s scars more noticeable.

Some of the beneficial treatments for undereye dark circles and fine lines include laser treatments, chemical peels, microneedling, PRP etc. Please visit a dermatologist. Based on your medical condition and other factors, the doctor will suggest the best treatment for you. 

The best thing to do is seek advice from a dermatologist who can make the correct diagnosis and administer treatment. They could suggest treatments in the form of topical or oral prescriptions and lifestyle modifications that will help you control your symptoms

Skin melanin treatment surgery can be harmful in the long run so I suggest not to go for it. You can try other treatments like chemical peels or dermabrasion instead. These treatments can help lighten the skin and are not harmful in the long run. Also using moisturizer and sunscreen can help.
