It seems that the burn is rather extensive and does not heal well. I would suggest early consultation with a dermatologist or burn specialist. Do not use any more cream and let the wound dry. It is essential to keep the wound well cleaned, dressed and treated. Seek medical help at the earliest.

Worry does not leave marks on your skin. Howe­ver, it may cause restle­ssness. Restless pe­ople sometimes scratch or bump into obje­cts. This can result in bruises forming. Fee­ling tense weake­ns your body's defenses. A we­akened immune syste­m makes bruising more likely. To pre­vent stress-relate­d bruising, you should find ways to relax. Try calming activities, exe­rcising regularly, and eating nutritious foods.

Hair loss can be due to several factors such as stress, unhealthy diet, or hormone variations. It's normal for humans to shed up to 100 strands of hair daily.

The numerous factors that lead to skin allergies on the backside and legs include irritants, allergenic agents, infection or autoimmune disorders.

Hair going white with age or being genetic is a usual thing. Skin problems and tension also cause this. Do something for yourself if under stress; take deep breaths maybe start doing yoga. Have a balanced diet rich in vitamins and minerals as they play a crucial role in preventing premature greying. If possible use plant-based dyes because they don’t contain harmful chemicals however; don’t forget to handle your hair gently while dying it so that you may not end up damaging it further. 

Bruising and discomfort after sclerotherapy are natural which normally resolves within a few days. But since you said your veins look worse and are more visible after the procedure could indicate a complication. It's good that you have already spoken with your doctor, but still experiencing discomfort or have any concerns, follow up with them promptly. 

In some cases the veins may fade on their own over time, but if the issue is related to the sclerotherapy procedure, additional treatment can be needed. Its best to follow up with your doctor to discuss your options and determine the best treatment.
