Actinic keratoses that develop on the lips are referred to as actinic cheilitis. The clinical appearance of an actinic keratosis is that of a small (several millimeters), red scaly papule or plaque, with induration and thickening of the epidermis. There may be associated erythema.

The vast majority of pulled calf muscles will heal completely within a few weeks without any treatment. Pulled muscles are also called muscle strains. They occur when muscle fibers are stretched beyond their normal length. The injury creates tears in the muscle that are usually tiny (microtears). In the most severe calf muscle strains, the entire muscle is torn, causing significant swelling and pain.
