Usually, they occur on your hands and feet and can be itchy and painful. However, they can also form on any other part of your body .
The reasons for their formation can be heat, rubbing, or skin diseases. Blisters on skin usually heal on their own without any medication. Read on to know the causes of this disease and the treatment options you have.
Are Blisters Serious?
Medical practitioners refer to a raised skin area filled with fluid as a blister or vesicle. If you've ever spent an extended period in ill-fitting shoes, you're definitely familiar with blisters.
Blisters form when contact between your skin and the shoe causes the skin layers to separate and fill with fluid, which is a typical cause of blistering.
Blisters are frequently irritating, inconvenient, or painful. However, they usually don't indicate a serious condition and will go away on their own. Anytime you have unexplained skin blistering, you should seek medical attention to get a diagnosis.Additional Read: Oral Psoriasis Symptoms
