Hello. Thank you for asking at Chat Doctor. I went through your history. I would like to ask you a few more questions like - what is your age? Did you have similar complaints in past? Do you have any other allergies? Do you have any digestion/gastric-related complaints? Do you have any other medical condition or do you take any medicine on regular basis? However, from your given history, I would like to make suggestions to you as follows:1. Were I treating you, I would prescribe you an antihistamine like cetirizine/levocetirizine/HY Chat Doctor. 2. I would suggest you to avoid hot spicy foods for a few days.3. Personally I would suggest you to avoid wearing tight-fitting or woolen clothes for a few weeks. Loose-fitting, cotton clothes will be the best option in my opinion.4. I would suggest you not to scratch when you itch as scratching aggravates the condition. I would suggest you to apply a lotion like calamine to the areas that itch.5. If above measures do not help, I would suggest you to go for some investigations like complete blood count, ESR, CRP, urine and stool examination, thyroid testing, etc. However, the tests can be decided only after detailed information about your symptoms. Hope above suggestions will be helpful to you. Should you have any other query, please feel free to ask at Chat Doctor. Wish you a fast recovery and the best of the health. Thank you & Regards.
