My heart goes out to you, as you're trying to make some sense of what it is you're feeling.
I know this is going to sound a little weird but working out if the tingling is normal is something worth questioning. For example, does it come with any other feelings/symptoms or does it happen on its own? The reason for using the word 'normal' is based on the idea that people actually look for a buzzing feeling in the hands and feet or all over body in certain practices like yoga, meditation, Tai Chi etc. Based on the concept of being able to feel your own physical energy, typically the hands and feet are the first place you'll feel it (that buzzing sensation). In these practices that buzzing or tingling is considered normal, unless it's accompanied by troublesome issues. As I say, I know this all sounds a little weird.
It's strange to think that we typically don't notice what the energy in our body is doing until we notice what it's doing. In other words, we don't notice that subtle buzz in our body that's happening at a subatomic level, we don't notice our heart beat or rate or our throat muscles and so on until something triggers the whole lot into hyper activity. Then we may feel tingling or buzzing in different parts or our body, we may feel our heart beat intensify and speed up to the point where we can almost hear it (it's so intense) and we may feel our throat muscles tighten, all through the state of intense anxiety/mental and physical hyperactivity.
So, after all that, is what you're feeling energy but you're only noticing it for the first time or is it something more than that? Is there something else going on (an indicator of the body's unease or dis-ease)? The body is definitely a highly intelligent thing, often sending us signals, sometimes trying to get our attention for good reason. Deciphering those signals/that information can definitely be a challenge at times.
I hope you find the answers you're looking for.
