pulsatile tinnitus or am i going mad?

[gainz]

Recently i came off a really bad cold. My right ear suddenly became blocked. I thought nothing of it. after a week i started to hear my own heart beat in my ear. I spoke to my gp they said its nothing its just earwax blocking the ear drum use oil drops. So i did it got better. Than recently it came back and i went to the gp for and emergency appointment. The doctor told me that the pulse in my ear is normal and that its anxiety and i told her what about when i lay down to sleep? she said everyone has it, its nothing to worry about. She looked in my ear and said oh it might be infected im going to give you some antibiotic spray. The spray has made it worse now I have no idea what to do. I think the doctor just wanted to get rid of me (my gp is trash by the way). But, when i use oil drops im fine and it goes away. Im i going mad? because when i explain it to people they look at me as if i have. Any suggestions would be great. And i would also like to say i used a lot of cotton buds in the past which i have stopped now. sometimes we get so busy with life we forget about our health and the little things. This got deep real quick. Anyway im waffling to much...
