Welcome
@Sandyusmc
I don't have the right words to say, cause I can relate. I wish it would stop. Its,,,,,no good.
I also have like high pitch scream with pulsing sounds like some insect, inside my head.
I looked up Cicadas songs, wiki. Their faster. Mine T is with my heart rate.
Some days I come home from work, its pulsing worse, Is it stress,,,,Stop the stress.
Yeah, the Doctor, meds, anti-depressants. Sleep as well as you can. Avoid stress, rest? Work with the medical people, what else do we have. Things will come around with a routine and distractions. Do you have any thing in life that you get enjoyment from? Even if you don't enjoy it, try, you should enjoy it. If so, take some time out for that. If not, have a glass of beer/wine, or do both. God Bless, things will get better. It has for me. It takes time.
