those unreimbursed medical expenses are deductible on schedule A; HOWEVER, only the portion that is over 7.5% of your wages are ultimately deductible....
So let's say your income is $40,000.
7.5% of $40,000 is $3,000.
so only the remaining $4,000 of the $7,000 you asked about would ultimately be deductible.
(and it gets more complicated as unless you have enough other deductions - state taxes, donations, etc - to exceed the 'standard deduction', it won't matter in any event )
