The process can take a while, depending on how quickly the agency can collect your medical records. Call all your medical providers and alert them to the fact that Social Security will be requesting your records. Always fill out forms promptly and send them back so that you can get a decision as quickly as possible. Go to all appointments that are scheduled for you and be as honest as possible about your condition.
If you do not have insurance and cannot work full-time, filing for benefits can be a big help in both realms of needing treatment and income. If you are found eligible for Social Security benefits, within two years if the condition persists, you can become eligible for Medicare, which will pay most of your hospital and doctor bills. If you meet the income threshold for Supplemental Security Income, you can be immediately eligible for Medicaid, which will also cover prescriptions for your condition as well as medical bills. Be persistent in pursuing your claim and as honest and open about your problems as possible so that you can be found eligible if your condition is severe enough.
