hives following bowel movement

Dear doctor,
I have experienced hives (intensely ithcy, bumpy skin) after somes bowel movements for about two years.  This has slowly increased in frequency but always has been a very intense response.  It nows is causing me a lot of concern.  My skin all over my back and legs and sometimes neck becomes very itchy and red shortly after a bowel movement.  This urticaria lasts for about 15 minutes and slowly subsides.  This does not happen every time I use the bathroon but when it does it is a very painful experience.  I am otherwise in very good health, 39 years old with no other problems except exercise induced asthma and itchy skin when I exercise.  This itching with exercise improves after I have exercised consistently for a number of days.  Also, I never sweat very much.  I do get pretty severe gas occasionally.  
Any advice or direction on who to see would be most appreciated.

Hello - thanks for asking your question.

What you are describing is known as urticaria (hives) - it affects up to 25 percent of the population.  I an unaware of a disease that causes hives in the setting of bowel movements specifically.  The following are among the potential triggers for urticaria:

Physical contacts
Stinging insects
Foods and additives
Thyroid disorders
Two rare genetic disorders, familial cold autoinflammatory syndrome, also called familial cold urticaria, and the Muckle-Wells syndrome can also cause urticaria

Basic laboratory tests includes a CBC with differential and erythrocyte sedimentation rate (ESR).  Biopsy of the urticarial lesions would also be considered.

As for a specialist, I would suggest an allergy/immunology referral which would help in the evaluation.  

Followup with your personal physician is essential.
