The anal swelling that occurs after standing for a long time is considered to have the symptoms of hemorrhoids or prolapse, due to the weakness and poor elasticity of the anal raphe or pelvic floor muscle groups. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. If you’re an older man with an enlarged prostate, take oral finasteride tablets and other medications. Avoid prolonged standing and sitting for long periods of time, and do anal lifting exercises or lower limb strength exercises to help strengthen the pelvic floor muscles and the muscles around the anus.
