welcome to Healthcare Magic.
Your symptoms may be related to anxiety
. Anxiety disorders can manifest with not only psychological symptoms but with a variety of physical symptoms also like: Tingling
, hot and cold sensations, palpitation
, tremors (shakiness) etc.
In history you mentioned that, you already had excessive worry/fear and crying spells, which are also symptoms of anxiety. I can understand your concern but anxiety should be considered in your case specially in presence of normal tests reports.
It is better to get evaluated by psychiatrist
and start treatment accordingly. For long term control of anxiety following measures are helpful: relaxation exercise, medicines like SSRIs and non drug treatment like CBT.
Wish you all the best.
