Detailed Answer:
Hi,
Thank you for your query.
1. You seem to have a form of Dermatographism or pressure induced hives.
2. Does the red area on touch turn into a flare (surrounding area becomes red) and then a wheal (raised area of skin)? If so, then this is known as the 'Triple response of Lewis'. This inflammatory response is due to histamine. Hence Zyrtec (Cetirizine) and Benadryl (Diphenhydramine) help in bringing it under control.
3. Your recent gain in weight by 20 pounds may be due to steroids. You may have rebound hives if steroids have been discontinued. Have your thyroid hormone levels and antibodies been checked?
4. You are correct in checking for autoimmune disorders. These usually involve auto antibodies to IgE and its receptors. There is a possibility that the specific autoimmune process is not discovered. Treatment of autoimmune hives will follow similar medications such as antihistamines, anti-leukotrienes (such a montelukast, zafirlukast) Monoclonal antibodies (omalizumab) , steroids, immune suppressants (such as Azathioprene and Cyclophosphamide), intravenous immunoglobulin (IvIg) and plasmapheresis.
5. Hives due to hormonal imbalance should have presented earlier before menopause.
6. It is also worthwhile to check for Food Intolerance which is IgG based (as against immediate hypersensitivity which is IgE based and checked by the needle tests).
I hope that I have answered your queries. If you have any further questions, I will be available to answer them.
Regards.
