I have been having this pain for more than 7 months. It is intermittent, poking like pain on the right side muscle that is under the armpit. There is no pain on the back. It all started from a severe flu/cold last winter.
The doctors don't know what could have caused this. Some think it was nerve damage. Others think it might be soft tissue. I have gone through physiotherapy, massage, acupuncture, cupping, Chinese medicine, you name it, but none worked. I don't feel more or less pain when I use the muscle. I do feel it more if I had bad night sleep or mentally stressed. If I touch the area gently with like a comb I feel some tingling but not the same type of pain and not severe. I also had a ultra sound and there was nothing obvious with it.
I recently noticed if I massage the muscle from back to front with some force, deep inside I could feel some up-down-direction string like thing that would bump my finger. Not sure if it was just normal muscle nods or something relevant. Could it still be some infection or inflammation? I don't feel it. There is nothing on the skin as well.
I am really running out options, and patience as well.. It becomes more and more a mental challenge. I had been a healthy male, 35 years of age, doing regular exercises, rarely eating junk food, and do 8+ hours of sleep every night. I really don't know what I did to deserve this.. Please help! Thank you!
