Hi
Welcome to the MedHelp forum!
The pinching sensation could be a weird perception of itch. Petechiae and capillary breaks are unlikely to cause them.
This looks like urticaria or hives. Urticaria is usually triggered by allergens, such as drugs, foods, insect bites, inhaled substances, in response to sunlight, cold, heat, stress, exercise, or a viral infection. Other common allergens are pollen, mold, dust, pet dander, or cosmetics. Since you experienced an itch, just go over these possibilities in your mind. Something may strike you. In many cases, hives clear up themselves and don’t require diagnosis or treatment. However if they persists you may need to see a specialist called an allergist to determine what is causing the reaction. Fungal infections also come up whenever there is moisture or temperature difference and Tinea versicolor can cause whole body itch. Over the counter antihistamines help. Calamine lotions and other over the counter preparations with camphor/menthol do help to reduce the itch. Try a soft cotton ball dipped in cool water applied over the itchy areas instead. Calamine lotions and other over the counter preparations with camphor/menthol can be applied after the cool water application.
Try and consult a skin specialist. Take care!

They sound like hemangiomas, which physician's insist do not cause pain. They are little red dots (not raised) level with the skin surface. Well, I had a few on the chest several years ago and went to the dermatologist and, yes, they "pinched". You bettcha. They are in fact broken capilaries. The dermatologists shrugged their shoulders, looked at me as if I was a nut, and dismissed my complaint, Eventually the pinching stopped. Completely. So I have no advice to provide except to have them looked at by a dermatologist, but don't be surprised if they dismiss your complaints as psychological.
