What Are The Itchy Bite Marks On My Leg In The Morning?

Everyday when i wake up i find my legs full of bites, dont look like mosquito bites, but strange thing is that on my legs only. These bites are so itchi that i cant sit straight for more than a minute and bothers me atleast a week.



Can you advise what this could be and how can i get rid of this?



Rgds,
