I'm having this chest pain on the left side about 30 to 40 minutes after falling asleep, and it even comes with a bit of sweating. Once it starts, I can't find a comfortable position to sleep in without it hurting, so I've been sleeping in an easy chair for the past five days. I started taking Tonact TG for my high cholesterol, which is 290. I'm also on Thyronorm 75 and Telmisartan 40. My TSH levels and blood pressure are normal. Should I be worried about this chest pain and what should I do about it?
