I have rashes on my arms, sometimes they get itchy, especially when touched. I think it could be an allergy to some food ( mushroom, brinjal ? ) or bed bugs. Of late there s been too much of bugs in my apartment. They bite me all over during sleep. I wake up in the morning with big bumps all over my arms. The bump subsides after a while. However, I can see tiny bumps , a lot of them on both my arms and they get really itchy when touched. I feel fine within 3-4 of taking shower but after than the itching starts leading to me scratching it and piercing the skin. What can I do to get relieved of the issue?
