Neck and shoulder pain. Simultaneously.

Around 2012 pain started from left side of neck after 5 years it has spread to left shoulder and even right side of neck .Every time i rotate the neck or shoulder click sound pops out. I was given tetanus shot in 2006 and had many small wounds i ignored tetanus shots, finally took tetanus shot in 2014. Am i affected with tetanus disease, can the disease stay for 5 years. In 2016 had tonsillectomy for tonsil infection but even after surgery i still have throat irritation due to some throat nerves . I feel numbness in left shoulder and neck when I wake up from sleep . After x ray 2 years ago the orthopaedic said i had stiff neck. I am scared whether it is tetanus infection or lyme disease or some degenerative nerve disorder . The throat irritation, shoulder and left neck pain triggers simultaneously.
