<s>[INST] Okay, Bursitus.... 2 months now.... pain (not excruitation) in left shoulder and down half way on left arm.... Does not hurt when I play golf. It hurts when I turn head left or right.... Last night I had to replace two chandlier lights... Needed to use left hand to grab onto light, right hand to take out old bulb and replace it... On a scale of 1 to 10 pain level... it was a 10. When I was done, it was okay. Is this Bursitus??? [/INST] Hello, I have studied your case. It can be rotator cuff injury to shoulder which may need MRI for confirmation. Medication like methylcobalamine with muscle relaxant and analgesic will reduce pain, you can take them consulting your treating doctor. You may consult physiotherapist for further guidance. He may start TENS, or ultrasound which is helpful in your case. You may need to take rest for early healing. Also check your it B12 and it D3 in your blood. Hope this answers your query. If you have additional questions or follow-up queries then please do not hesitate in writing to us. I will be happy to answer your queries. Wishing you good health. Take disregards Chat Doctor.  </s>
