See hemangiomas usually don't cause pain and even if they cause it(in rare cases) presentation is not like yours.

See due to constipation food stagnates in our intestines this stagnated food is acted upon by a large number of harmful bacterias and pathogen which causes production of large amount of gases.These gases accumulate in intestines and compresses the nerves passing through its muscular walls this causes severe pain.Relieve in pain associated with position is usually related to gas only.
Accumulated gas can either pass through anus or mouth.When the gas reverts back to mouth passing through stomach and other areas it provokes nausea.

Radiation to back is also suggestive of this fact only.See the nerves in intestines when compresed causes pain to radiate to back(overlapping dermatomes).

Oatmeal Tea: When constipation is severe, this remedy is the best. Oatmeal is fibrous, Honey is healing and moisturizing, and Chamomile is an anti-inflammatory agent which soothes the stomach. Together, they can cure severe constipation. So, take a cup of water and add three teaspoons of oatmeal, a Chamomile tea bag and two teaspoons of honey. Drink 2-3 times a day if your problem is severe.
Lemon: Lemon contains citric acid, which has the ability to stimulate the function of digestion in your body. The action of lemon on your digestive system enables it to get rid of the toxins and undigested material that generally accumulates on the colon's (the last part of your small intestine) walls, giving rise to constipation as a result. Collect the juice of 1 lemon in a cup by squeezing it. Fill the rest of the cup with warm water. Drink it every morning.
