SSI and Medicaid are income & resource based. Depending on what your bf's income is, you could lose medicaid & you could lose a portion of your SSI. You get Medicaid because SSA found you disabled and eligible for SSI. Any money he gives you and/or any of your bills that he pays could go against you.
You will stay in the hospital 1 to 3 days after the operation. In most cases you should be able to go back to your normal daily activities in 1 to 3 weeks. If your appendix ruptured or an abscess formed, you will need to stay at the hospital longer and it will take more time to recover. If you have a drainage tube, it will be removed when the infection has cleared up.
The length of your hospital stay depends on the type of operation and how your recovery goes. If you got implants, the average hospital stay is 1 to 2 days. Flap procedures may require a stay of 5 to 6 days. After you go home, you can expect some soreness, swelling, and bruising for 2 to 3 weeks.
