Ive had lower pack pain for over a week after helping move boxes in my office.  Today the pain is mostly on the right side and whenever I take in a breath, the pain is very sharp.  Sitting is uncomfortable and so is lying down.  Standing is the most tolerable.  No fever, no vomiting.  I drink nothing but water, no pop, no coffee.
Dear patient, Thank You for choosing Chat Doctor. I do understand your concern. What happened to You may be muscle soreness or muscle injury after lifting weights. In the case of the soreness it means that your muscle are getting stronger in that area. In the case of the injury, which is the most probably situation of your suffer, I will suggest not to worry too much, because the muscle will regenerate itself. Give your organism its own time, helping it with proteins and sugar in your diet. Also consider massaging, or swimming in hot pools. If you can not afford this, please let the hot water run in that area that aches while you are in douche. Cover it up with some topical anti-inflammatory cream and consider buying some muscle patches that are stuck in your skin and do not let the muscle move, giving it time to regenerate. I think these are found in your nearest Chat Doctor. Consider
