Thanks for the input, oldandtired, but I have to disagree with your impressions.
First off, you don't have to start paying back your student loans until you are completely finished with your residency. You could comfortably pay off the interest as you go. And, as a resident, you will make roughly what an average podiatrist will make 1, 2 and 3 years out. You will probably make something like 40-42k in your first year, mid 40's in your second and it will increase to around 50 or so by the time you are in your last year. And, your hours will be decreasing every year. A podiatrist, by contrast, can expect to work at least 60-70 hours a week if he/she even hopes to make 60-80k gross (meanwhile paying back the student loans, saving up an additional 15% in taxes because of self-employment designation and, if they decided to start up their own practice....well, that would be unwise).
I think that you are also buying into the podiatry mantra of low hours and high pay. That is utter hogwash. I think what gets confusing is that very few podiatrists have emergency call and, thus, do not work horrible hours. This IS true, but their income reflects it.
And, another huge difference between you and us is that YOU ARE GOING TO HAVE JOB OFFERS WHEN YOUR ARE FINISHED! Podiatrists generally DO NOT have any realistic job offers when they finish their residencies and end up doing very unglamorous work for a pittance. Oh, and one other thing....when you finish your residency, you're going to command a salary around 180k to 225k!!!!! I mean, c'mon!! Radiologists are one of the most highly paid medical specialties around. And, your hours are not going to be too ridiculous.
FP's and internists do 3 years of total residency. Most podiatrists do 2 years. An FP or internist is likely to command a salary of around 100k when they finish (no matter what part of the country they work in). A podiatrist is going to make between 35 and 45k in the first 1-3 years. And, may I also point out that it is HIGHLY unlikely that an FP or internist is going to open up their own practice from the get go. This is because they don't have to and have a reasonable number of jobs to pick from (with perks like health insurance, malpractice insurance, parking, vacation, etc., etc., paid for). A podiatrist will be lucky to find a decent job in the first 6 months post-residency and this job WILL NOT pay for health/malpractice insurance and will probably not take on an associate as an "employee" since they have to pay your self-employment tax. This is also a very big difference.
And just as an addendum, in California, where I practice, our beloved governor is trying to push through some legislation that would omit podiatry from Medi-Cal (Medi-Caid everywhere else). I'd say that this pretty much sums up the lack of respect that we endure all of the time compared to MD's and DO's. Do you think that any governor in any state is going to introduce legislation to eliminate radiologists from the payroll???? I really doubt it. If I lost Medi-Cal, I'd lose about 40% of my income. This would be a deathblow to a lot of DPM's.
So, I'm not sure if you were serious about trying to favorably compare your situation as a radiology resident (which I would pay money to be right now) with a podiatrist, or you are just trying to get a rise out of us! Either way, welcome to the podiatry forum!
