<s>[INST] Hey. I am a hairstylist. I have been for 4 years. LAtely I have been experiencing a tight feeling in chest. And a tingling so to speak sensation in my back, near my shoulder blade. I do not know if these two things are related, but it seems when my arms Are raised to chest height or higher, the tightness and weird feelings are worse... Is this a pulled muscle?? [/INST] Thanks for your question on Healthcare Magic.I can understand your concern. Yes, possibility of muscular spasm related chest tightness is more likely.So better to follow these steps for better symptomatic relief. 1. Apply warm water pad on affected areas of chest. 2. Take painkiller and muscle relaxant drugs like ibuprofen and thiocolchicoside.3. Take calcium and vitamin d 3 supplements because deficiency of these can also cause muscle spasms.Don't worry, you will be alright with all these. Avoid stress and tension, be relax and calm. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
