Hello~Maybe when you had the mammogram, it pinched a nerve,which could certainly cause the tingling sensation. Have you asked your GP about this? Possibly, seeing a chiropractor might help, he/she will take some x-rays of your spine, study them and go over the results with you, if they think they will be able to help, they will give you an adjustment, after a few treatments, you should feel better.
My mammogram tech sometimes seems to grab part of my arm and shoulder and leaves my neck uncomfortable so it is entirely possible something got pinched. There are lab tests, EMG and NCV for example ,that can evaluate nerve function. (Often those tests are ordered for workers who think they might have job-related carpal tunnel syndrome.) If you ask your PCP about testing I would suggest not going into the suspicions about the mammograms. PCP may want to get neck xray done first. I would steer clear of chiroprachters for this type of issue.
I'm personally really glad you had a mammogram! That's important.
Tingling does usually mean compression of a nerve. You can do stretches which can often help. Look up "shoulder rotations" and "neck raises" for instructions on a couple of stretches that are known to help with tingling hands and nerve compression. Your insurance doesn't cover chiropractors (mine doesn't either) but does it cover a physical therapist? That's another specialty that can really help with what you describe.
Your hand is still shaking with a tremor occasionally? We can have that happen due to stress and anxiety as well as something like low blood sugar.
Hopefully it goes away this time like it did last. Talk to your doctor about it even if it is gone at your next physical.
My aunts are in their 90's and love those health news letters from questionable sources lol. Recently they sent one home with me, and it did give me pause.
It was about the symptoms of Parkinson's, one of which was involuntary tremors, the thumb specifically being mentioned.
I am experiencing this in my left thumb. I also experience a sporadic involuntary motion in my left wrist/elbow. And, lol, my left eye occasionally twitches.
I have a few other symptoms from the Parkinson's list, but I also have the classic pin pricks in my fingers of diabetic neuropathy or carpal tunnel or cubital tunnel or joint impingement/constriction....
Then again, my UTI was mistreated with a drug called Macrobid which started a whole phalanx of never before experienced neuropathic symptoms.
Or, my TIA's could explain the one-sidedness of my symptoms.
[ps my breast mri flexed my head backward so far that my hands were dead to all sensation long before they were done imaging-I could not tell I had hands unless I was looking at them!]
Which just goes to show our symptoms could be coming from anywhere or everywhere. I don't know about the rest of you but even with insurance I can't afford to investigate everything under the sun so I just catalog everything while I wait and see what happens next.
