Had a c-section with spinal block 5 weeks ago n have been plagued w bad hives all over torso ever since esp. where clothing touches skin. what to do?

Hives post spinal: You should contact your doctor to report this untoward reaction and get advice for treatment.

Antihistamines: Taking antihistamines on a regular basis, such as zyrtec, (cetirizine) will help to reduce the frequency and severity of the hives. Hives are sometimes induced by an infection, surgery, or other biophysical stressor.

See your doctor: Did the hives start while you were still feeling the effects of the anesthesia? You probably received a lot of different medicines during a c-section, including antibiotics and pain medications such as morphine. If you are still having hives weeks later, you should see an allergist to determine exactly which medications you might be allergic to. Treatment with steroids might be needed.

Not spinal : Sounds to me like a contact dermatitis. Nothing you got from the spinal is still "around" to cause a rash. See your pcp or a dermatologist.
