Since childhood i have had a very itchy skin and very often find that my arms & legs and other parts of my body will start itching for no reason, and it sometimes it starts with a little red dot but when i itch, it becomes like hives and all red. Sometimes i will get itchy and the hive like things will stay and then sometimes it will start itching right next to that and spread and takes a few days to disappear. I find that this happens to me more in summer and sometimes in exposed areas like neck arms, also very often i will feel an insect like sharp burn or bite and i fing there are small little lines on itching become hives.This itching also extends to my genital areas. I do have dry skin and i do not use soap and use lotion every day, i sometimes have anti-allergic tab if the itching is bad and i make sure i try and wear cotton close to my skin. Yet i cant undestand it as it is very uncomfortable and i can wear sleeveless vest or shorts or skirts as my skin feels itchy....... and often looks read or has previous marks etc. Any advice.?
