I m 44 years old and recently hurt a muscle training my shoulders. The muscle pain is in my upper back between my spine and shoulder blade. I have iced it many times and the pain is almost gone but now my right triceb is lame and weak is that a nerve thats damaged aswell
Hi, When a patient complains about muscle weakness and sensory changes in this case upper limb (triceps) the doctor first looks at this part where you have the pain (UPPER BACK) to see if a patient have a pain in the nerve roots.  If pain is in upper back doubt is in the roots of the nerves but if the pain is not there, doctor with looks for the other muscles that have same innervation with the muscle that feels weakness in this case n. radialis to look for weaknesses: extensors of the wrist and fingers and looks for sensory changes in the parts that n. radial gives sensation. I suggest you consult a physician. Hope I have answered your query. Let me know if I can assist you further. Take care Leonard, Physical Therapist or Physiotherapist
