Internal tear healing

So my daughter was born august 4th. However, she came down the canal so fast that she caused an internal tear on my left side. It’s been 6+ weeks and I still have a major aching on that side when I stand or walk for too long.. sometimes when I sit in certain positions as well. I wasn’t told much about the healing of the internal tear, so I don’t know if it’s normal to ache like this? It’s just so difficult because I want to take her on more walks and activities throughout the day but I find myself having to leave places early due to not being able to stand anymore. Can anyone tell me about their internal tear healing experiences? Also regarding sex and how it felt the first time you did it/how long you waited after birth?
