Hi @gabrielm! Thanks for getting back to me. I was told by the doctors to use breathing techniques such as breathing with your “stomach” like the singers. You basically have to inhale and expand your stomach by counting till 4 and exhale through your mouth by counting till 6. This is actually the right way for people to breathe, not with the chest. Also, i was told to do meditation to relax the upper muscles in order to calm the breathing. If i do intense cardio exercises when i am able, i have managed to track my heart rate which can go up between 150-190. It is good to test your heart from time to time. However, i am thinking of making an appointment for MRI and maybe also visit gastroenterologist just to exclude any issues perhaps related to parasites. I would like to check also if maybe something is not right with the diaphragm. I wanted to ask you if you have your issue when you are sleeping? Also, did they tell you any specific diagnosis? Did they call your breathing issue dyspnea? The only thing in my blood test results that i have is a slight increase of my white blood cells( the norm is about 5% and mine are 6%). Did they also run some blood tests on you? Greetings from Austria
