Hello,
Thank you for posting your query at DoctorSpring.com
I saw your pictue.
It looks like a boil. You need Antibiotic like Clindamycin capsule along with anti inflammatory tablet. It comes down. You can take Tab. Advil for pain. You will need prescription for the medicines.
Bleeding per rectum can be due to Fissure in ano or haemorrhoids. You should take high fiber diet, plenty of liquids, fresh fruits and vegetables. The stool should be soft.If there is no response, you should consult your Surgeon and proceed.
Pain after eating depends on the food you take.There will be pain if you eat spicy food. Acid peptic disease will also cause pain. I prescribe Proton pump inhibitor like Rabeprazole to my patients with similar complaints. It is really effective in relieving the pain of acid peptic disease.
Nothing to worry.
Hope I answered your query.
If you have any questions, I will clarify further.
Wish you good health.
Regards
