I have been getting bouts of intense anxiety on my cycle. I can be just sitting there and if I become mentally stressed...my arm pits will begin to drip sweat?! I also am getting strong pulse sensations from my heart beating hard. I can literally take my pulse anywhere on my body?! What the hell...
I had the same thing with my shoulder....I am a physical therapist and did shoulder stability and RTC exercises after resting the bicep tendon and shoulder for 3 months
(Lots of ICE, CFM, US) no weights... with light stretching only. Unfortunately, it came back again despite gradually...
