Any profession pays you lesser when you start as a fresher. And as your work experience increases, your pay check also gets better and it also depends on where you work. For example, working in a Super speciality or a Multi Speciality pays you more than working in a clinic. But in general, more or less, these 3 professions pay the same package for freshers. It is usually 15-20k for freshers a month and as the experience increases the pay also increases. On an average with 2-3 years of experience, critical care salary is 3,50,000Rs per annum which is approximately 25,000-28,000 Rs per month. It is more or less the same for PTs and OTs too. It might be around 4,00,000Rs per annum.
