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.
Blood Clots. A blood clot needs to be considered as a cause of calf pain, especially when the calf pain is not the immediate result of an injury. Blood clots can form is the deep veins of the leg, causing a blockage in circulation. This may cause swelling and pain in the calf.
Runners and other athletes are also prone to calf tightness, as the calf muscles are constantly firing to stabilize the ankle and both absorb each landing and push the heel back off the ground. Interestingly, calf tightness can also be symptomatic of weakness elsewhere in the leg. If your glutes and/or hamstrings are weak, your calves will often try to make up for that weakness, which means the muscle gets overused, which in turn exacerbates calf tightness.
