Hello dear, may I know your age? usually pain around neck and lower back is because of sponylosis in patients after 45 years of age. In es earlier age group it could be because of disc problem. You require regular exercise, proper posture and some medicine in case of acute pain. Rest is mandatory in acute painful conditions.

Since you have not mentioned your age. But you have been working out shows you must be in young to middle age bracket probably. Ideally if there is pain only during specific activities then probably it's the mechanical pain which arises due to wrong posture and weak musculature. You should see someone for muscle strengthening exercises and some ergonomic training. Also you should do a guided workout. Regards.
