Past week, foot/body stiffness when getting out of bed and after sitting for 3-5mins. some quick numbness. no change/injury. anything i can do to help?

Foot/ body stiffness: Just the foot or body also ? If foot may be plantar fasciitis, - treat w/ stretches ( roller massager can get online) or kinesiotape, NSAIDS ( motrin if not allergic) or input/meds /steroid injections from doc. If body stiffness, see doc-check for infection(strep- also have fever or ST), post exercise(charley horse), autoimmune process-check ESR,CRP ANA,TSH, H pylori (GERD), check for MS
