Ive been dealing with constant headaches and itching all over my body. Sometimes it feels like thousands of needles are being injected into my skin, and I also have red marks in some areas. The problem seems to be getting worse day by day. What could be causing this and how can I get some relief?

You may be experiencing symptoms of an allergic reaction. To address the itching and redness, you can take an antihistamine such as Cetirizine (10mg) once daily. For the headache, you can take Acetaminophen (500mg) as needed for pain relief. However, it is important to identify and avoid the trigger causing your symptoms. If the symptoms persist or worsen, please seek medical attention for further evaluation and management.
