hi,
thanks for the brief history of you.
as you mentioned you have the symptoms of
tingling and also you have done a heavy shoulder workout. which makes me close to the cause of it. It may be a pinched
nerve in the spine. for which you can take an
MRI if the symptoms increase and find the extent of
injury to the soft tissues. Also performing the slow core stability and spinal muscle Strengthening exercises will help you ease the system.
also to understand the biomechanics of spine here as when you do sqatting there is a big open window for the inter
vertebral disc to move. which can lead to pinching of the nerve and provide any sensory and motor symptoms.
Also, when next time you do heavy shoulder workout please make assure you learn the proper technique to life.
as in many cases one may make the spine in danger. So to safeguard the spine is the first priority of any action sports or physcial activity.
With the grace of God I wish you a good health
