The above is an important post

Your post is important because most people are silent on personal issues and we are not told enough by doctors.

Clove oil is too strong for the skin. Every tiny tear will irritate more when urinating or applying anything strong. Don't scratch. Don't use soap. Don't use toilet paper. Use plain water to rinse well and a good mild oil and blot the excess with a soft cloth that doesn't contain detergent residue. Do this before sleep and when sleep is disturbed.

Don't sit too long. Sweat hurts. Get a good donut cushion and use it with only a little air in it. Lie down and open your legs whenever you can. Stretch and exercise for the endorphins. Drink lots of clean water and eat lightly. Only vegetables and mild fruits juices and broths watering them down.

Get a little sunshine.
