Last week after i finished exercising, my heart beat did a weird thing two or three times where it felt like someone was squeezing it a little. this week after my climb, it was happening every 3 beats or so for a minute - very uncomfortable.

Work with the Dr.: Doctors doing in-person care are needed. A college-aged guy can visit his doctor to see what's going on. If it is due to heart lining inflammation, an arrhythmia, thyroid excess, anxiety, the doctor can evaluate and refer to specialists as needed. In one's early 20's, heart and lung diseases are uncommon compared to in middle-aged or older adults. Better to avoid caffeine or other stimulants.
