Take here to the doctor, we are not a medical advice website.

Ulcer is fully curable even without taking medicines.
If anyone really has ulcer pls let me know. I will cure it online just by acupressure

your doctor is the only person qualified to advise you on this question
go talk to him

That can be serious for you. It sounds like you have already seen a doctor, and it may be worth having a second opinion.

Pseudomonas can become resistant to antibiotics, and often a specimen from the infection will be tested by a lab to determine which antibiotic is going to work best.

There is a range of possible antibiotics which the doctor may choose from:
ceftazidime

ciprofloxacin or levofloxacin

gentamicin

cefepime

aztreonam

carbapenems

ticarcillin

ureidopenicillins

In addition that ulcer may imply trouble with the blood circulation in your legs (which might be old news to you), so ask about treatment for that from the doctor.

Above all, don't neglect this or try to manage it by yourself.

Urbanization is the process of the growth and development of urban areas, which refers to the concentration of human settlements with high population density, economic activity, and infrastructural development. Here are some of the advantages of urbanization:

1. Economic growth: Urbanization promotes economic growth by creating a conducive environment for business and industry to thrive. This is because urban areas tend to have better infrastructure, access to capital, and a larger workforce, which leads to increased productivity, job creation, and economic growth.
2. Improved quality of life: Urbanization often leads to an improved quality of life for residents. This is because urban areas tend to have better access to healthcare, education, and other essential services, as well as greater cultural and recreational opportunities.
3. Technological advancement: Urbanization can drive technological advancement by promoting innovation, research and development, and technology transfer. This can lead to the creation of new industries and jobs, and improve the overall competitiveness of the economy.
4. Social diversity: Urbanization promotes social diversity by bringing people from different backgrounds, cultures, and social classes together. This can lead to greater social cohesion and understanding, and promote tolerance and mutual respect.
5. Environmental benefits: Urbanization can also bring environmental benefits, as it can promote the development of sustainable infrastructure and practices, such as public transportation systems, green buildings, and renewable energy sources.

Overall, while urbanization can have some negative impacts, such as congestion, pollution, and social inequality, it also has several advantages that contribute to the growth and development of society.

It may be necessary to use a compounding pharmacy to use a anti-bacterial that will treat the ulcer. If he has been to a specialist I assume that the ulcer has been cultured and tested for susceptibility. If the proper antibiotics are being administered then a typical corneal ulcer should heal.
If the ulcer has been cultured and treated accordingly then there are other factors that are causing the ulcer. There is a possibility of the problem being caused by the Herpes Simplex virus or Ocular Cicatrical Pemphagoid.
Have your son see a corneal specialist, if that isn't one of the specialists he has seen. To give you a better answer I would need a fuller picture of the previous diagnosis's, cause of the ulcer and treatments that have been attempted already. Good luck with your son. I hope this helps.
