Can I effectively treat mild psoriasis?

The transparent liquid you see coming out is likely pus, a sign of infection. Try cleaning the wound daily with mild soap and warm water, then apply an antibiotic ointment. Keep it covered with a bandage to protect it. If it doesn't improve in a couple of days or if you notice increasing redness, swelling, or warmth around the wound, it's best to seek medical help. 

Jellyfish stings are common and can leave scars, swelling, and itching even after the pain subsides. Applying antihistamine creams can help with itching and oral antihistamines are recommended for swelling. If symptoms persist, a local methylprednisolone injection may be considered. It's best to avoid swimming and running until the scars heal to prevent further irritation.

If you have dark spots on your face, which could be caused by your sebaceous glands being blocked or the skin gathering too much pigment, they probably are. Face cleaning and protection from the sun are the two main prevention methods for infinite spots. You want a cream that includes retinol, A, not to forget vitamin C, to ensure it will lighten the color in time. 

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. 

To help the wound heal, ensure that you keep it clean and dry, wash the area gently with some mild soap and water then dry. Any rough movements which might disrupt the stitches should be avoided. Consult with Your Doctor on the right type of vitamin C use, usually white because colored ones could have added ingredients. Should there be signs like increased pain, redness, swelling, or pus, then do seek medical Help immediately as this could mean infection.
