I am diabetic and single no medical must paid cash what can I claim

You can claim this against "amounts not recovered by medical aid" Usse TaxTim to help you complete your return and we will show you where to put these amounts.

and if I dont have any medical cover I pay cash for every thing out of my owen pocket and also for my hospital coverage and doctors.

It is the same thing on the return, just titled like that.

but even my dentist and hospital payments cause I lost my long life friend and he passed away about 3jrs now and he used all the medical aid, thats why I cant aford any medical aid I only work for a salary and that 's all I dont even got anything from his estate.

Anything where a doctor or tests are involved can be claimed as out of pocket expenses for tax purposes. For medicines they need to be prescribed by a doctor for them to be claimable.
