Tetanus disease comes with some toxic dirty cuts that make swallowing very hard as well as stiffness of muscles generally.

Blackheads are minuscule black spots on your skin. They are a result of oil and dead skin blocking the pores on the skin. To clarify them, gently wash the pores once daily, never neglect the exfoliation part, and the third thing is to apply a non-come-genic moisturizer. Besides you can try using salicylic acid or benzoyl peroxide products. Don't forget to wash your face thoroughly and moisturize it.

When certain allergies occur, body parts tend to swell. This might have been caused by contact with something like a plant or chemical that does not agree with you.

If the pain persists, medical assistance should be sought to determine the exact cause and receive the appropriate treatment.
