My heart rate is 98bpm, it used to be much lower than this. I have chest pains on and off throughout the day & I sweat a lot recently (i feel hot a lot whereas i used to feel cold all the time) but otherwise I am quite fit & I'm vegetarian & eat really healthy. Could this be pancreatitis? Or something similar? I drink alcohol, usually 1 bottle of red wine over the weekend (1/2 a bottle sat, 1/2 a bottle Sunday) no other alcohol & I don't drink during the week.
