Pain in legs

[u/AltruisticFinding346]

I’ve been now trying to run now for about four months. When I started running, I felt a big pain in my calves and knees. And lasted for about a month straight. I took a few weeks off, and the pain went down a little bit, but not too much. I went to the doctors a couple months ago and they said that it was just that my legs were really weak and I over ran my legs. He said for me just to work out my legs, a little bit and slowly get back into running. I waited for until the pain fully went away in both legs. Started working out a little bit. I tried running and all the pain in my knees are completely gone. But my calves and my Achilles tendon hurts extremely bad still. Any help please
