Symptoms of hyperthyroidism. I consult?

I am facing all symptoms of hyperthyroidism. I have scheduled a thyroid test for tomorrow but I believe I have it because my mother has it too. My weight has reduced to significant levels, muscle and legs pain too much, abnormal heart rates occasionally. Also I am facing premature ejaculation even before sex. My fingers also shiver and I feel weak. Due to ongoing situation of covid-19 I am unable to visit the hospital but I believe I can get some help online. My weight and appetite has always been an issue but it sort of improved last year and I gained weight. But suddenly now I am facing all these conditions. Also I am a regular inhaler consumer as I have breathing problem. I am prescribed Maxiflo 250 inhaler. Kindly advise as to what steps I should take. I am looking for a good endocrinologist. Is it wise or whom should I consult?
