<human>: if i do any physical activities my body  experiences burning feeling with rashes all over the body and severe itches. I referred several doctors they said it is because of some allergy but cannot be diagnosed, they prescribed me with cetrizine tablets, I am taking it for nearly 10 years so became addict to those tablets.  so please help me to come out of my disease and tablet addicting problems...........
<bot>: Hello. Thank you for asking at Chat Doctor. I went through your history. I would like to ask you about your symptoms in great detail, like - what are the activities that precipitate itching & rashes, whether they occur without any activity as well, whether you have any other medical conditions, whether you are taking any other medicines on regular basis, whether you have any other allergies, etc. etc. However, from your history, I would first think of what we call "Cholinergic urticaria". It is not exactly due to "allergy", rather it is due to some physical factors which causes rashes and itching. Were I treating you, I would suggest you as follows:1. Please avoid exercises and activities causing excessive sweating, if possible.2. Please avoid bathing in hot water, sauna baths, exposure to hot temperatures, etc. However, if any of these does not cause you symptoms, you can continue with it.3. I would suggest you to avoid hot beverages, alcohol and hot-spicy foods as much as possible.4. If you are having mental/emotional stress, I would suggest you regular meditation and stress reduction techniques as it also can be aggravating your symptoms.5. If you are not comfortable with cetirizine, I would personally suggest you to take ketotifen, which works better for these types of urticaria.6. Please do not scratch when you itch, it will only aggravate itching. You can apply lotion on itchy areas. An important thing I want to mention here is please do not think of "addiction" of antihistamines. These types of urticaria usually last for several years. So as long as you have symptoms, you need to take antihistamines like cetirizine. Hope above suggestions will be helpful to you. Wish you the best of the health. Should you have any further query, please feel free to ask at Chat Doctor. Thank you & Regards.
