Hi,Dear,
Thanks for the query to HCM. I studied your problem in depth and I understood your concerns.
Cause and plan of Treatment-
In my opinion on the given data,you seem to have throbbing which is normal and not due to any allied lump,in your case.As rightly observed by you even you can't feel lump or hardness but only throbbing and your CT is normal.It may be because of
high BP and hyperdynamic vascular dance in the jugular notch.
So keep cool and Consult your ER Physician who would treat your high Bp if its there , or would find out the cause for your
anxiety and ER Surgeon for opinion, if need be , who would treat it accordingly.
So don't build up wrong concepts and create more psychic complications in you which would increase risks and costs to you, but just ask a query to HCM and be comfortable to resolve your health issues.
Welcome for any more query in this regard to HCM.
Write good reviews and Click thanks if you feel satisfied with my advise.
Have a Good Day.
Dr.Savaskar M.N.
