I am a bigger person but it isn t chest pain. anything I should be concerned about or can take to help? [/INST] Hi,Thanks  for  your query.The symptoms you have described are more likely to be symptoms of muscles strain.To get relief from the pain and for quick healing:1. Do hot fomatation at the site.2. Apply local anti-inflammatory gel 2-3 times a day.3. Take anti-inflammatory drugs like Ibuprofen to reduce pain and local swelling or inflammation.4. Do not lift weight or try to do exercise that involve painful muscles. Give proper time to heal.I do hope that you have found something helpful and I will be glad to answer any further query.Take care </s>
