I am sorry to hear you are struggling with some challenging physical symptoms.
Stress and worry can certainly cause all kinds of strange body sensations.
I would recommend that if you have not done so already, you go to your GP to discuss this.
Unusual physical sensations can cause further stress and thus create a vicious circle between mind and body.
Hopefully your GP should be able to alleviate your physical concerns with specific tests if needs be.
There are other things we could recommend for nervous tension etc but it is always wise to get symptoms checked out first.
If the cause seems to be stress related do contact us again if you would like any further information about what may help.
With best wishes and hope your symptoms ease soon.
