Hi Doctor, Yesterday morning I woke up with red rashes on my legs, arms, and back. Im not sure if its from something I ate or if its from something else. After lunch, I noticed more rashes appeared, but they went away after some time. In the morning, I also experienced a lot of itching, and when I scratched the rashes, they started to spread. Could this be an allergic reaction or something else? What should I do about it?

You may be experiencing an allergic reaction. To help alleviate the itching and rash, you can take an antihistamine. Additionally, you can apply a soothing lotion like Calamine lotion to the affected areas to help reduce the itching and inflammation. If the symptoms persist or worsen, it is advisable to consult a healthcare professional for further evaluation and management.
