Microwave heat packs are one of the best mean to help eliminate cramps and endometriois   The warmth from the wheat pack can help relax the muscle tension and relax abdominal musles to reduce  pain caused by muscle spasms 
 
This pelvic heat pack is shaped so it covers the required adnominal area where some individuals have issues. I have been told that is easily slips inside of  pajama bottoms and stays in place while sleeping or resting. 
 
This pelvic pack is filled with Alberta grown wheat and has a removable washable flannel cover making it an hygienic product.  The removable cover is finished  with French seams to prevent fraying during washing. The inside is sewn in baffled chambers so the wheat stays in place and the heat is evenly  distributed.    Warm repetitively in the microwave to enjoy long-lasting heat.
 
This wheat pack can also be put in the freezer and used as an Ice pack.  Some individuals prefer to use a cold pack in relieving pain.   Place this pack into the freezer in a plastic bag for a few hours and it is now ready to use. 
 
The inside portions of the wheat pack is not washable.
