dont want to hijack the topic, but do you wear your wader tight? have a heavy vest/vest in general? or bad seated posture all the time? cause i worked out a lot and sit behind the computer too much, and i have very tense upper back most the time, that is why i wear my wader straps loose, and changed from a vest to waist pouch. or my upper body starts burning and my arm goes to sleep, while i get cramps under my rod arm's shoulder blade. no i am fine, i can fish 9 hours straight np.
