Can black blood clotting on wound be treated?

You have been suffering from allergic rhinitis (hay fever) for the last two years. Symptoms like sneezing, running nose, and congestion can be very annoying. Usually, the things that trigger this allergic reaction are pollen, dust mites, or pet dander. Antihistamines like Montas-L can help you by blocking the allergy response and thus, reducing the symptoms. The regular intake of your medication is necessary for the proper control of your allergy.

Your skin might be affected by acanthosis nigricans which is identified by dark patches, even on the throat and joints. Being overweight and having high blood pressure are risk factors for this. The treatment is to lose weight and control the BP, as a result, the patches can be healed. Follow a healthy diet, exercise regularly, and be consistent with your prescribed medications to control your blood pressure.

Dark skin patches and acne can occur due to sun exposure, hormonal changes, or clogged pores. To improve your skin, use gentle cleansers, keep your skin moisturized, and avoid harsh products. Drink plenty of water, eat healthy food, and resist picking at acne to prevent scarring. Also, protect your skin from the sun to reduce further darkening.

Swelling on hand that keeps filling with fluid or pus could be due to an infection, possibly from a cut or insect bite. When it drains and fills back up, it could indicate an ongoing infection. It's important to keep the area clean and dry to prevent further complications. I recommend gently washing the area with soap and water, applying a clean bandage, and keeping your hand elevated to reduce swelling. However, if the symptoms persist or worsen, it's best to seek medical attention for further evaluation and possible antibiotics. 

It appears as though you possibly have an extremely bad allergic reaction on your podophylin cream. I suggest that you go to a dermatologist immediately for an assessment and treatment.
