Now her thyroid is ok But since November she has moving chest pain and backside headache.. We had done her tests ecg echo , blood test ..hrct scan..cervical spine and all results are ok. Her bp is also normal Doctor says it can be neuro muscular pain which can be a side effect of not taking medicine for a month and have suggested cap caldikind plus, tab bon dk 60000 ..tab laregab nt, tab lanol er , tab oxetol 50..its been a week..but no change in her pain.. We are feeling helpless now..which doctor to go which specialist to check with Please guide she is also tired visiting different doctors God bless 🙏
