Aches and pains from lying in bed?

[Infowars87]

The past three months my anxiety has caused me to mostly lie in bed most days and I've been going out more frequently lately including walking my dog three times a day and have realized that the more I move I am experiencing chest pain , low and mid back pain along with leg pain throughout the days. The chest pain is a heaviness in the middle and I've had a EKG and chest x ray done three weeks ago that came back good. Could these aches be caused by becoming active again!

Yes. Three months of inactivity is sufficient to cause muscle atrophy. I get soreness the next day or two if I skip working out for a couple of weeks.
