Hello, Thanks for posting in HCM. Kindly do not use medications with expired date already. Use pressure pads on eyes. You can buy same new eye drops as were prescribed to you previously. Take paracetamol tablet for headache and also to keep fever low if at all it comes due to infection. It will also help reduce the inflammation. Use and see for not more than 5 days. If there is no improvement in that time then kindly see ophthalmologist as soon as possible as the injury could be worse than before. It will actually advisable to show the doctor right now but if you feel it’s same as before then you can wait for few days due to your insurance problem. I hope I have answered your query well. If you have any more question kindly write back to me, will be happy to help you out. Thank you
